json包含单双引号问题解决方案http://www.bieryun.com/1197.html
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”
分享给大家

效果DEMO：
JsonQuotesUtil.js
[javascript] view plain copy
/**
* 解决json传输数据时存在 同时存在单引号和双引号的问题
*
* 思路：
*
* 1 首选将 双引号转义
*
* 2 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
*
* 注：可以传入字符串 也可以传入字符串数组

demo.js 使用范例：

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

/* 使用方法1 创建对象并自定义 单双引号占位符
var jsonQuotesUtil = new JsonQuotesUtil().setSingleQuotePlaceholder
("%^^").setDoubleQuotePlaceholder("&&");//创建对象(同时自定义单双引占位符)*/
/* 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 jsonQuotesUtil = new JsonQuotesUtil();//创建对象使用默认单双引号占位符
*/
var jsonQuotesUtil = new JsonQuotesUtil();//创建对象使用默认单双引号占位符
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)!="")
{
jsonQuotesUtil.setSingleQuotePlaceholder(single);//设置单引号占位符
}
if($.trim(double)!="")
{
jsonQuotesUtil.setDoubleQuotePlaceholder(double);//设置双引号占位符
}
var reuslt = jsonQuotesUtil.replaceSingleAndDoubleQuote(sourceStr);//同时替换单双引
号
// var reuslt = jsonQuotesUtil.escapeDoubleQuote(sourceStr)
$("#replaceResult").html(reuslt);//显示替换后的字符串
});
$("#escape").click(function(){
var sourceStr =$("#sourceStr").val();//获取需要替换字符
var reuslt = new JsonQuotesUtil().escapeDoubleQuote(sourceStr);
$("#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）
{
var jsonQuotesUtil = new JsonQuotesUtil();//创建对象使用默认单双引号占位符
var sourceStr = new Array();
sourceStr[0]="dfdfd'dfdf";
sourceStr[1]="dfdfd\"sfdsfsd";
alert("sourceStr"+sourceStr);
var reuslt = jsonQuotesUtil.replaceSingleAndDoubleQuote(sourceStr);//同时替换单双引
号
alert( "after:"+reuslt);
