Javascript转义字符串中的所有单引号 [英] Javascript escape all single quotes in string

问题描述

我想将html存储在json中，为此我将html字符串化.

I want to store html in json and for that i stringify the html.

问题是我不能替换所有单引号.

Problem is that I can't replace all single quotes.

这是我的代码:

<div id="myHtml">Men's and Women's something.</div>

和js:

function save(){
    item = {}
    dataTemplate = []
    item['html'] = $('#myHtml').html().replace(/'/g,"\'"); // not working
    // tried with .replace(/'/g,"\\'"); but I don't want two \\
    // this is broken .replace(/'\/g,"\\'")
    dataTemplate.push(item);
    alert(JSON.stringify(dataTemplate));
}

我还能怎么做?

推荐答案

问题不会被替换，这是JSON.stringify处理反斜杠的方式.因此，如果您在字符串转换后进行替换，它将起作用.

Issue is not replace, it's how JSON.stringify treats a backslash. So if you do your replacement after stringify it'll work.

例如

function save(){
    item = {}
    dataTemplate = []
    item['html'] = $('#myHtml').html();
    dataTemplate.push(item);
    a = JSON.stringify(dataTemplate);
    a = a.replace(/'/g,"\\'");
    //alert(a);
    console.log(a);
}

save();

<div id="myHtml">Men's and Women's something.</div>
