JSON to URL Parameters

I need convert json object to url form like: “parameter=12&asd=1”

I done with this:

        var data = {
            'action':'actualiza_resultado',
            'postID': 1,
            'gl': 2,
            'gl2' : 3
        };

        var string_=JSON.stringify(data);

        string_=string_.replace(/{/g, "");
        string_=string_.replace(/}/g, "");
        string_=string_.replace(/:/g, "=")
        string_=string_.replace(/,/g, "&");
        string_=string_.replace(/"/g, "");

But i wonder if there any function in javascript or in JSON object to do this?

jQuery provides param that does exactly that. If you don’t use jquery, take at look at the source.

Basically, it goes like this:

url = Object.keys(data).map(function(k) {
    return encodeURIComponent(k) + '=' + encodeURIComponent(data[k])
}).join('&')

2019 update: there’s now a built-in object URLSearchParams for this type of thing:

let myParams = {'foo': 'hi there', 'bar': '???'};

let u = new URLSearchParams(myParams).toString();

console.log(u);

前端回车(换行)显示成空格

请求到的字符串渲染到html页面,换行通常没有我们想要的换行效果 ,除非你把字符串放在<pre>标签中 ,这是因为文本中的回车是'\n''\n\r',而html中的回车是<br />

但是<pre>标签通常会出现一个致命的问题,在手机端没法响应式(responsive)的显示,我的解决方法是添加white-space属性。

<p style="white-space: pre-line">
  {{text}}
</p>
