Believe that the front-end development of friends have suffered this torture: when the HTML is connected by the hateful single quotation marks, double quotes to get dizzy. Like what:
element.innerhtml = ' <a href= ' + URL + ' "onclick=" alert (\ "+ msg + ' \ ');" > ' + text + ' </a> ';
Here is a string format function:


String.Format = function (str) {
var args = arguments, re = new RegExp ("% ([1-" + Args.length + "])", "G");
return String (str). replace (
Re
Function ($, $) {
return args[$2];
}
);
};
The invocation method is simple:
element.innerhtml = String.Format (' <a href= '%1″onclick= ' alert (\ '%2\ '); " >%3</a> ', URL, msg, text);
