json包含单双引号问题解决方案

原创作品  转载请注明出处


最近项目中  遇到需要JSON传数据  但是某个字段 里面可能含有 双引号和单引号  导致出现错误


为了方便 写了一个工具类,比较好用。

支持“链式编程”

/**

 * 将 单双引号用不容易在字符串中出现的字符分别替换
 * 在后台 分别用过单双引号替换掉即可

demo.js 使用范例:

$(function(){

    //替换单双引号按钮的点击事件
    $("#show").click(function(){

        var sourceStr =$("#sourceStr").val();//获取需要替换字符

        /* 使用方法2 自定义对象并自定义 单双引号占位符
           var jsonQuotesUtil = new JsonQuotesUtil();//创建对象使用默认单双引号占位符
          jsonQuotesUtil.setSingleQuotePlaceholder("%^^");
          jsonQuotesUtil.setDoubleQuotePlaceholder("##");*/


         // jsonQuotesUtil.restoreDefaults();//恢复默认的单双引号占位符


        /* 使用方法3 自定义对象并自定义 单双引号占位符

        var single =$("#single").val();//获取 单引号占位符
        var double = $("#double").val();//获取输入的双引号占位符

        if($.trim(single)!="")

         $("#replaceResult").html(reuslt);//显示替换后的字符串



    });


    function arrayTest()//支持数组每个字符串的替换(没有调用)
