如何使用变量作为json属性? [英] How to use a variable as a json atribute?

问题描述

您好，我在一个通用函数中工作，该函数根据选择的内容发送ajax请求:

Hello im working in a generic function that sends an ajax request according with the selection made:

$('#selectAcao, #selectAno').change(function(){
    var sthis = $(this);
    var sthisTipo = sthis.attr('rel');
    var sthisName = sthis.attr('name');
    var params = {
        "tipo": sthisTipo,
        sthisName : sthis.children('option:selected').val(),
        "atualiza" : true
    }
    $.atualizaSelect(params);
});

我想要做的就是将"sthisName"变量作为"param"中的属性传递:

All I want is pass a "sthisName" variable as a property in "param":

    var params = {
        "tipo": sthisTipo,
        sthisName : sthis.children('option:selected').val(),
        "atualiza" : true
    }

我该怎么做?

推荐答案

那不是JSON. JSON是一种数据序列化格式.您拥有的是一个JavaScript对象文字.

That isn't JSON. JSON is a data serialisation format. What you have is a JavaScript object literal.

无法在创建JavaScript对象时使用变量来定义属性名称.

There is no way to define a property name using a variable at creation time for a JavaScript object.

您必须先创建对象，然后添加属性.

You have to create the object first, and then add the property.

var myObject = {};
myObject[string_containing_property_name] = some_value;
