在ajax调用的参数中传递变量

How can I pass the variables in the parameters of ajax call. Below is the example to clarify my question:-

如何在ajax调用的参数中传递变量。以下是澄清我的问题的例子: -

function updateSingleParameters(name,varName, varValue)
{
$.ajax({
    type: 'POST',
    url:name,
    data: {
        varName: varValue
    },
    success: function(data, status){
        alert("Data: " + data + "\nStatus: " + status);
    }

});

I need varName also to be treated as a variable but it is treated as a constant when I execute the script.

我还需要将varName视为变量,但在执行脚本时它被视为常量。

Kindly suggest.

Thanks in advance.

提前致谢。

Create an object and set the property name with the varName variable using [] syntax.

使用[]语法创建一个对象并使用varName变量设置属性名称。

function updateSingleParameters(name,varName, varValue)
{
    var data = {};
    data[varName] = varValue;
    $.ajax({
        type: 'POST',
        url:name,
        data: data,
        success: function(data, status){
            alert("Data: " + data + "\nStatus: " + status);
        }

    });
}

The basic idea is create an object and set the key with bracket notation.

基本思想是创建一个对象并使用括号表示法设置键。

var data = {};
data[varName] = varValue;
$.ajax({
    type: 'POST',
    url:name,
    data: data,
    success: function(data, status){
        alert("Data: " + data + "\nStatus: " + status);
    }

});

In your function, I think if you do:

在你的功能中,我想如果你这样做:

   function updateSingleParameters(name,varName, varValue)
   {
     var passToAjax = varValue;
      $.ajax({
         type: 'POST',
         url:name,
         data: {
         varName: passToAjax
       },
       success: function(data, status){
       alert("Data: " + data + "\nStatus: " + status);
       }

     });

I think it would work better. But i'd need to see your HTML also to make sure that it is the problem. Also, the file where you send the ajax.

我认为它会更好。但我还需要看到你的HTML,以确保它是问题所在。此外,您发送ajax的文件。

Construct the object separately.

单独构造对象。

function updateSingleParameters(name,varName, varValue)
{
var obj = {};
obj[varName] = varValue;

$.ajax({
    type: 'POST',
    url:name,
    data: obj,
    success: function(data, status){
        alert("Data: " + data + "\nStatus: " + status);
    }

});
