JS获取地址栏制定参数值:
//获取URL参数的值 function getUrlParam(name){ var reg = new RegExp("(^|&)"+ name +"=([^&]*)(&|$)"); var r = window.location.search.substr(1).match(reg); if (r!=null) return unescape(r[2]); return null; }
JS去除空字符:
String.prototype.trim=function() { return this.replace(/(^\s*)|(\s*$)/g,‘‘); } var str=" test "; alert("["+str+"]"); // [ test ] alert("["+str.trim()+"]"); // [test]
JS字符串格式化:
/** 格式化输入字符串**/ //用法: "hello{0}".format(‘world‘);返回‘hello world‘ String.prototype.format= function(){ var args = arguments; return this.replace(/\{(\d+)\}/g,function(s,i){ return args[i]; }); } var str = "hello{0}{1}".format(‘world‘,‘haha‘); alert(str);
