jQuery .on（）方法在Firefox上而不是在Chrome上(jQuery .on() method woking on Firefox but not on Chrome)

 我正在尝试在我的网页上创建一个特定的功能，它使用jQuery迭代JSON对象，使用其值填充组合框，并使用jQuery的.on()方法将click事件处理程序附加到选项。  
 在我决定在Google Chrome上测试功能之前 ，一切似乎都运行正常。 （到目前为止，我一直在开发Firefox Developer Edition）。 来自jQuery的.on()方法似乎根本不适用于谷歌浏览器。  
 这是我的网页的HTML代码段  
<div id="showotherinfo">
    <div class="form-group" id="existingRedirection" style="">
        <label for="serviceNameList">Select a Pretty Redirection to edit it, or add a new one below</label>
        <select class="form-control" id="serviceNameList" name="serviceNameList">
            <option value="0">-Add New-</option>
            <option value="57">Infibeam Redirection</option>
            <option value="53">Mozilla Developers Redirection</option>
            <option value="56">SnapDeal Redirection</option>
        </select>
        <hr style="height: 1px; border: none; color: #333; background-color: #333;">

        </div>
    </div>
    <div class="form-group" style="margin-top: 19px;">
        <label for="redirectType">Redirect Type<font color="red" size=3>*</font></label>

        </select> 
    </div>
    <div class="checkbox">
        <label style="font-weight: bold;">
            <input type="checkbox" name="nofollow" id="nofollow">
            NoFollow this link

    </div>
    <div class="form-group">

                class="btn btn-danger" onclick="resetValue()" style="margin-left: 45px;">Reset</button>
    </div>
</div>
 
 以下是完成所有工作的jQuery代码  
var $select = $('#serviceNameList');
var $firstOption = $("<option/>");
$firstOption.attr("value", 0);
$firstOption.text("-Add New-");

$firstOption.on('click', function() {
    $('#name').val("");
    $('#serviceUrl').val("");
    $('#prettyUrl').val("");
    $('#redirectType').val("");

    $('#nofollow').removeAttr('checked');

    $('#saveRIP').show();
    $('#updateRIP').hide();
    $('#delete').hide();
});

$select.append($firstOption);

$(jsonResponse).each(function (index, o) {    
    var $option = $("<option/>");
    $option.attr("value", o.id);

    $option.on('click', function()  {
        $('#name').val(o.service_name);
        $('#serviceUrl').val(o.service_url);
        $('#prettyUrl').val(o.pretty_url);
        $('#redirectType').val(o.redirect_type);

        if (o.no_follow == 1)   {
            $('#nofollow').prop("checked", true);
        }
        else    {
            $('#nofollow').prop("checked", false);
        }

        $('#saveRIP').hide();

        $('#updateRIP').show();
        $('#delete').show();
    });

    $option.text(o.service_name);
    $select.append($option);
});

if ($("#serviceNameList option:selected").val() == 0)   {
    $('#saveRIP').show();

    $('#updateRIP').hide();
    $('#delete').hide();
}
 
 这里是JSFiddle链接 - http://jsfiddle.net/6uy1quLg/5/ （尝试在Google Chrome和Firefox上运行它以查看差异）  
 从小提琴中可以明显看出，填充组合框的代码工作得很好， 但是对于附加click事件处理程序的代码似乎根本没有执行。  
 有人可以帮我解决这个问题吗？ 提前致谢。 

I am trying to create a specific functionality on my web page, which uses jQuery to iterate over a JSON object, populates a combo box with its values, and also attach click event handlers to the options using jQuery's .on() method. 
All seemed to be working fine, until I decided to test the functionality on Google Chrome. (I had been developing on Firefox Developer Edition till now). The .on() method from jQuery does not seem to be working on Google Chrome at all. 
Here is the HTML code snippet for my web page 
<div id="showotherinfo">
    <div class="form-group" id="existingRedirection" style="">
        <label for="serviceNameList">Select a Pretty Redirection to edit it, or add a new one below</label>
        <select class="form-control" id="serviceNameList" name="serviceNameList">
            <option value="0">-Add New-</option>
            <option value="57">Infibeam Redirection</option>
            <option value="53">Mozilla Developers Redirection</option>
            <option value="56">SnapDeal Redirection</option>
        </select>
        <hr style="height: 1px; border: none; color: #333; background-color: #333;">                                                    
    </div>
    <div class="form-group">
        <label for="name">Service Name<font color="red" size=3>*</font></label> 
        <input class="form-control" name="name" id="name">  
    </div>
     <div class="form-group">
        <label for="serviceUrl">Target URL<font color="red" size=3>*</font></label> 
        <input class="form-control" name="serviceUrl" id="serviceUrl">
    </div>
    <label for="prettyUrl">Pretty URL<font color="red" size=3>*</font></label>
    <div class="form-inline">
        <div class="form-group">
            <input type="text" class="form-control" name="prettyUrl" id="prettyUrl" >
        </div>
    </div>
    <div class="form-group" style="margin-top: 19px;">
        <label for="redirectType">Redirect Type<font color="red" size=3>*</font></label> 
        <select class="form-control"
            name="redirectType" id="redirectType">
            <option value="0" SELECTED>-Redirection Type-</option>
            <option value="307">Temporary(307)</option>
            <option value="301">Permanent(301)</option>
            <option value="302">Found(302)</option>
        </select> 
    </div>
    <div class="checkbox">
        <label style="font-weight: bold;">
            <input type="checkbox" name="nofollow" id="nofollow">
            NoFollow this link
        </label> 
    </div>
    <div class="form-group">
        <button id="saveRIP" type="button" class="btn btn-primary"
                onclick="saveData('save')">Save</button>
        <button id="updateRIP" type="button"
                class="btn btn-primary" onclick="saveData('update')"
                >Update</button>
        <button id="delete" type="button" class="btn btn-danger"
        onclick="saveData('delete')">Delete</button>
        <button id="resetRIP" type="button"
                class="btn btn-danger" onclick="resetValue()" style="margin-left: 45px;">Reset</button>
    </div>
</div>
 
And here is the jQuery code that does all the work 
var $select = $('#serviceNameList');
var $firstOption = $("<option/>");
$firstOption.attr("value", 0);
$firstOption.text("-Add New-");

$firstOption.on('click', function() {
    $('#name').val("");
    $('#serviceUrl').val("");
    $('#prettyUrl').val("");
    $('#redirectType').val("");

    $('#nofollow').removeAttr('checked');

    $('#saveRIP').show();
    $('#updateRIP').hide();
    $('#delete').hide();
});

$select.append($firstOption);

$(jsonResponse).each(function (index, o) {    
    var $option = $("<option/>");
    $option.attr("value", o.id);

    $option.on('click', function()  {
        $('#name').val(o.service_name);
        $('#serviceUrl').val(o.service_url);
        $('#prettyUrl').val(o.pretty_url);
        $('#redirectType').val(o.redirect_type);

        if (o.no_follow == 1)   {
            $('#nofollow').prop("checked", true);
        }
        else    {
            $('#nofollow').prop("checked", false);
        }

        $('#saveRIP').hide();

        $('#updateRIP').show();
        $('#delete').show();
    });

    $option.text(o.service_name);
    $select.append($option);
});

if ($("#serviceNameList option:selected").val() == 0)   {
    $('#saveRIP').show();

    $('#updateRIP').hide();
    $('#delete').hide();
}
 
And here is the JSFiddle link- http://jsfiddle.net/6uy1quLg/5/ (Try running it on both Google Chrome and Firefox to see the difference) 
As is evident from the fiddle, the code to populate the combo box is working just fine, but to code to attach click event handler doesn't seem to be executing at all.  
Can anybody please help me out regarding this?? Thanks in advance.

 我正在使用下面的代码，它对我来说工作正常。我也在Web API中使用它来以字符串形式返回View。  
 对于更多，你可以创建静态类 ，并使下面的方法静态。  
 public string RenderPartialView(string controllerName, string viewName, object model = null) {
     System.Web.HttpContextBase contextBase = new System.Web.HttpContextWrapper(System.Web.HttpContext.Current);

     var routeData = new RouteData();
     routeData.Values.Add("controller", controllerName);
     var controllerContext = new System.Web.Mvc.ControllerContext(contextBase, routeData,
      new EmptyController());

     var razorViewEngine = new System.Web.Mvc.RazorViewEngine();
     var razorViewResult = razorViewEngine.FindPartialView(controllerContext, viewName, false);

     var writer = new StringWriter();
     System.Web.Mvc.ViewContext viewContext;


     viewContext = new System.Web.Mvc.ViewContext(controllerContext, razorViewResult.View,
      new System.Web.Mvc.ViewDataDictionary(model), new System.Web.Mvc.TempDataDictionary(), writer);

     viewContext.ViewData["controller"] = controllerName;

     HttpContext.Current.Items.Add("controller", controllerName);

     razorViewResult.View.Render(viewContext, writer);

     string htmlString = writer.ToString();
     writer.Dispose();

     return htmlString;
    }
 
 
private class EmptyController: System.Web.Mvc.ControllerBase {
  protected override void ExecuteCore() {}
 }
 
 现在请找到我们如何从控制器调用它的例子。  
RenderPartialView("Home", string.Format("~/Views/Home/{0}.cshtml", "Index"));
 
 我希望这对你有用。 

I am using below code and it is working fine for me.i am also using it in Web API for returning View in form of string. 
For more you can create Static Class and make below method static. 
 public string RenderPartialView(string controllerName, string viewName, object model = null) {
     System.Web.HttpContextBase contextBase = new System.Web.HttpContextWrapper(System.Web.HttpContext.Current);

     var routeData = new RouteData();
     routeData.Values.Add("controller", controllerName);
     var controllerContext = new System.Web.Mvc.ControllerContext(contextBase, routeData,
      new EmptyController());

     var razorViewEngine = new System.Web.Mvc.RazorViewEngine();
     var razorViewResult = razorViewEngine.FindPartialView(controllerContext, viewName, false);

     var writer = new StringWriter();
     System.Web.Mvc.ViewContext viewContext;


     viewContext = new System.Web.Mvc.ViewContext(controllerContext, razorViewResult.View,
      new System.Web.Mvc.ViewDataDictionary(model), new System.Web.Mvc.TempDataDictionary(), writer);

     viewContext.ViewData["controller"] = controllerName;

     HttpContext.Current.Items.Add("controller", controllerName);

     razorViewResult.View.Render(viewContext, writer);

     string htmlString = writer.ToString();
     writer.Dispose();

     return htmlString;
    }
 
 
private class EmptyController: System.Web.Mvc.ControllerBase {
  protected override void ExecuteCore() {}
 }
 
Now please find example how we can call it from controller. 
RenderPartialView("Home", string.Format("~/Views/Home/{0}.cshtml", "Index"));
 
I hope this will be useful to you.
