使用Ajax将PHP值传递给javascript(Pass PHP value to javascript using Ajax)

 我有一个提供数据库值的PHP代码。 我需要javascript变量中的那些值。  
 Javascript代码  
<script src="http://code.jquery.com/jquery-1.8.0.js"></script>
<script type="text/javascript">
    function text() {
        var textVal=$("#busqueda_de_producto").val();
        $.ajax(
        {
            type:"POST",
            url:"index.php",  //here goes your php script file where you want to pass value
            data: textVal,
            success:function(response)
            {
               // JAVSCRIPT VARIABLE = varable from PHP file.
            }
        });

        return false;
    }
</script>
 
 PHP文件代码：  
<?php
    $q11 = "select * from sp_documentocompra_detalle where dcd_codigo".$_GET['codigo']; 
    $res11 = mysql_query($q11);
    $row11 = mysql_fetch_array($res11);
?>

I have a php code that provides the database values. I need those values in the javascript variable. 
Javascript Code 
<script src="http://code.jquery.com/jquery-1.8.0.js"></script>
<script type="text/javascript">
    function text() {
        var textVal=$("#busqueda_de_producto").val();
        $.ajax(
        {
            type:"POST",
            url:"index.php",  //here goes your php script file where you want to pass value
            data: textVal,
            success:function(response)
            {
               // JAVSCRIPT VARIABLE = varable from PHP file.
            }
        });

        return false;
    }
</script>
 
PHP FILE CODE: 
<?php
    $q11 = "select * from sp_documentocompra_detalle where dcd_codigo".$_GET['codigo']; 
    $res11 = mysql_query($q11);
    $row11 = mysql_fetch_array($res11);
?>

 由于observe选项的收集处理能力有限（所以你需要写"observe": [ "people[0].age","people[1].age", etc ]使它像你一样工作已经弄明白了）推荐的模式是为你的people收藏品使用create功能。  
 在您的自定义create创建函数中，您可以使用{ observe: ["age"] }作为映射选项再次调用ko.mapping.fromJS ，该选项将创建所需的项：  
var data = {
    people: [
        {id: 1, age: 25}, 
        {id: 2, age: 35}
    ]
};
var mappingOptions = {
    people: {
        create: function(options) {
            return ko.mapping.fromJS(options.data, { observe: ["age"] });
        }
    }
}
var r = ko.mapping.fromJS(data, mappingOptions);
 
 演示JSFiddle 。 

Because of the limited collection handling capabilities of the observe option (so you would need to write "observe": [ "people[0].age","people[1].age", etc ] to make it work as you've already figured it out) the recommended pattern is to use a create function for your people collection. 
In your custom create create function you can call ko.mapping.fromJS again with your { observe: ["age"] } as the mapping option which will create the required items: 
var data = {
    people: [
        {id: 1, age: 25}, 
        {id: 2, age: 35}
    ]
};
var mappingOptions = {
    people: {
        create: function(options) {
            return ko.mapping.fromJS(options.data, { observe: ["age"] });
        }
    }
}
var r = ko.mapping.fromJS(data, mappingOptions);
 
Demo JSFiddle.
