和 jquery-ui-1.8.16-custom：
(function() {
var script = document.createElement('script');
script.type = 'text/javascript';
script.src = '//pagead2.googlesyndication.com/pagead/js/google_top.js';
var head = document.getElementsByTagName('head')[0];
if (head) {
head.appendChild(script);
}})();
这个html文件有什么问题，它是"''"反斜杠吗？ 当我放一个字符串示例时它有效
thisString = thisString.replace(/Q/g, "''x51");
其结果是：''x51
我感谢任何帮助或调试
提前致谢
你不需要转义斜杠;"''x51"就足够了。
只是一个评论 - 大量的重复代码可以用基于String.prototype.charCodeAt的简单函数替换：
function replaceWithCode(s) {
var t = '';
for (var i=0, iLen=s.length; i<iLen; i++) {
t +='''x' + s.charCodeAt(i).toString(16);
}
return t;
}
replaceWithCode('A9$'); // 'x41'x39'x24
我想你在这里缺少多行模式m修饰符：
thisString = thisString.replace(/Q/mg, "''x51");
