jQuery往cookie里存数据:
$.cookie('inspect_id', inspect_id,{ path: '/' }); // 存储 cookie
jQuery从cookie里取数据:
var r = $.cookie('inspect_id'); // 取出 cookie
js编码:
encodeURI("测试"); // %E6%B5%8B%E8%AF%95js解码:
decodeURI("%E6%B5%8B%E8%AF%95"); // 测试
>日期格式化:
//格式化日期
Date.prototype.Format = function(fmt)
{
var o = {
"M+" : this.getMonth()+1, //月份
"d+" : this.getDate(), //日
"h+" : this.getHours(), //小时
"m+" : this.getMinutes(), //分
"s+" : this.getSeconds() //秒
};

} >跳转不产生历史,即后退不会返回到当前页面:
window.location.replace(baseJS+"/view/modelbs/task/jsp/inspectionRecord.jsp");//检查记录页面
>获取url参数方法一(加有编码,前台encodeURI,只能获取最后一个参数):
//获取URL参数
function getQueryStr(str){

//获取参数
function getParams(){
var disableStr=getQueryStr("Bx");
if(disableStr!=null&&disableStr.toString().length>1) {
var base_id = decodeURI(disableStr);
alert(base_id)
}
}>获取URL参数方法二:
//获取页面参数
function getQueryString(name){
var reg = new RegExp("(^|&)"+name+"=([^&]*)(&|$)", "i");
var r = window.location.search.substr(1).match(reg);
if (r!=null&&r!='null'){

}

}>上一个页面是变化的时候获取地址(比如有参数)
