[英]How can I build a json string in javascript/jquery?
I would like to build a json string programmatically. 我想以编程方式构建一个json字符串。 The end product should be something like:
最终产品应该是这样的:
var myParamsJson = {first_name: "Bob", last_name: "Smith" };
However I would like to do it one parameter at a time. 但是我想一次做一个参数。 If it were an array, I would just do something like:
如果它是一个数组,我会做的事情如下:
var myParamsArray = [];
myParamsArray["first_name"] = "Bob";
myParamsArray["last_name"] = "Smith";
I wouldn't even mind building that array and then converting to json. 我甚至不介意构建该数组然后转换为json。 Any ideas?
有任何想法吗?
You could do a similar thing with objects: 你可以用对象做类似的事情:
var myObj = {};
myObj["first_name"] = "Bob";
myObj["last_name"] = "Smith";
and then you could use the JSON.stringify
method to turn that object into a JSON string. 然后你可以使用
JSON.stringify
方法将该对象转换为JSON字符串。
var json = JSON.stringify(myObj);
alert(json);
will show: 将会呈现:
{"first_name":"Bob","last_name":"Smith"}
This method is natively built into all modern browsers (even IE8 supports it, even if IE8 is very far from being a modern browser). 这种方法本身内置于所有现代浏览器中(即使IE8远非现代浏览器,IE8也支持它)。 And if you need to support some legacy browsers you could include the json2.js script.
如果您需要支持一些旧版浏览器,可以包含json2.js脚本。
Create a normal object: 创建一个普通对象:
var o = {
first_name: 'Robert',
last_name: 'Dougan'
};
And then use JSON.stringify
to make it a string: 然后使用
JSON.stringify
使其成为一个字符串:
var string = JSON.stringify(o); //"{"first_name":"Robert","last_name":"Dougan"}"
