///// <summary>
///// Produce a string in double quotes with backslash sequences in all the right places.
/////
///// 常用的用法：String.Format("{0}.setValue({1});", ClientJavascriptID, JsHelper.Enquote(Text))
///// 大部分情况下，可以使用 GetJsString 函数代替此函数
///// 此函数返回的是双引号括起来的字符串，用来作为JSON属性比较合适，一般用在OnAjaxPreRender
///// 但是作为HTML属性时，由于HTML属性本身就是双引号括起来的，就容易引起冲突
