jquery plug-in source code:
/** * 对jquery中$.ajax进行封装,以便加入锁屏功能 * isAsync 是否为异步请求,默认为true * isLock 是否锁屏,默认是true * isCache 是否从浏览器缓存中加载信息,默认是fasle ***/ ;(function($) { $.fn.doPost = function(settings) { settings = jQuery.extend({ isAsync:true, type : "post", url : null, dataType : null, data : null, success : null, error : toError, isLock : true, isCache : false }, settings); $(this).each(function(){ if(settings.isLock){ lockSrc(); } $.ajax({ async:settings.isAsync, type:settings.type, url:settings.url, dataType:settings.dataType, data:settings.data, cache:settings.isCache, success:function(msg){ if(settings.isLock){ unlockSrc(); } settings.success(msg); }, error:settings.error }); }); //锁屏方法 function lockSrc(){ $(".lockDiv").css({"opacity":"0.5"}).fadeIn('normal'); var scrollWidth = document.documentElement.clientWidth;//document.body.clientWidth; var scrollHeight =document.documentElement.clientHeight; // document.body.clientHeight; var divWidth = $(".lockDivInfo").width(); var divHeight = $(".lockDivInfo").height(); var divLeft = scrollWidth/2-divWidth/2; var divTop = scrollHeight/2-divHeight/2; //console.log("bodyWidth="+scrollWidth+",bodyHeight="+scrollHeight+",divHeight="+divHeight+",divWidth="+divWidth+",left="+divLeft+",top="+divTop); $(".lockDivInfo").css({"position":"absolute","top":divTop,"left":divLeft}).fadeIn('normal'); } //解屏方法 function unlockSrc(){ $(".lockDivInfo").fadeOut('normal'); $(".lockDiv").fadeOut('normal'); } function toError(){ alert("操作失败!"); } }; })(jQuery);
Lock screen style:
/* 锁屏 */ .lockDiv { width: 100%; height: 100%; display: none; z-index: 10; background-color: #DFE8F6; position: absolute; top: 0px; left: 0px; } .lockDivInfo { width: 50px; height: 2px; display: none; position: absolute; left: 0px; top: 0px; z-index: 11 } #CloseDiv { float: right; width: 100px; height: 100px; margin-top: 10px; margin-right: 10px; }
<div class="lockDiv"></div> <div class="lockDivInfo" > <img id="CloseDiv" src="/hnhd/images/circle_animation.gif"></img> </div>
