正确解码包含c＃\ u003c或\ u00252等字符串的文本(Properly decode a text that contains strings like \u003c or \u00252 in c#)

 我有一个JSon响应，里面包含很多\ u003c或\ u00252或其他类似的字符串。 我需要一个合适的函数才能将这些字符串解码为正确的字符。 

I have a JSon response that contains lots of \u003c or \u00252 or other similar strings inside. I need a proper function in order to decode these strings into proper characters.

 为了增加输入和标签字段的ID和FOR，您可以使用： 
 

 .attr（attributeName，function） 
 

 在你的CSS你需要改变： 
 

.field-r input[type="radio"]#coming-yes+label {
   cursor: url('/assets/images/happy.png'), pointer;    
}
.field-r input[type="radio"]#coming-no+label {
   cursor: url('/assets/images/sad.png'), pointer;  
}

 

 至： 
 

.field-r input[type="radio"].coming-yesRadio+label {
    cursor: url('/assets/images/happy.png'), pointer;
}
.field-r input[type="radio"]..coming-noRadio+label {
    cursor: url('/assets/images/sad.png'), pointer;
}

 

 相反，要在CSS中通过id来处理每个元素，您可以使用一个类。 这意味着将相应的类添加到您的输入元素。

$('.addguest').on('click', function(e) {
    e.preventDefault();
    //
    // get the current number of ele and increment it
    //
    var i = $('.guest').length + 1;
    $('.guest').first().clone().find("input").attr('id', function(idx, attrVal) {
        return attrVal + i;  // change the id
    }).attr('name', function(idx, attrVal) {
        return attrVal + i;  // change the name
    }).val('').removeAttr('checked').end().find('label').attr('for', function(idx, attrVal) {
        return attrVal + i; // change the for
    }).end().insertBefore(this);
});

In order to increment the IDs and FORs of your input and label fields you can use:
 

.attr( attributeName, function )
 

In your css you need to change from:
 

.field-r input[type="radio"]#coming-yes+label {
   cursor: url('/assets/images/happy.png'), pointer;    
}
.field-r input[type="radio"]#coming-no+label {
   cursor: url('/assets/images/sad.png'), pointer;  
}

 

To:
 

.field-r input[type="radio"].coming-yesRadio+label {
    cursor: url('/assets/images/happy.png'), pointer;
}
.field-r input[type="radio"]..coming-noRadio+label {
    cursor: url('/assets/images/sad.png'), pointer;
}

 

Instead to address each element by id in your CSS you may use a class. That means to add the corresponding class to your input elements.
 

The snippet:
 

 

 
 
 
  
$('.addguest').on('click', function(e) {
    e.preventDefault();
    //
    // get the current number of ele and increment it
    //
    var i = $('.guest').length + 1;
    $('.guest').first().clone().find("input").attr('id', function(idx, attrVal) {
        return attrVal + i;  // change the id
    }).attr('name', function(idx, attrVal) {
        return attrVal + i;  // change the name
    }).val('').removeAttr('checked').end().find('label').attr('for', function(idx, attrVal) {
        return attrVal + i; // change the for
    }).end().insertBefore(this);
});
