JS页面延迟执行一些方法(整理)

复制代码 代码如下:

//延迟查询，传一个查询btn的ID，然后根据它附近的FORM绑定，当FORM里面的控件被触发或被输入了就会500毫秒后模拟点击查询按钮
var timeout;
function searchTrigerInit(btnId){
var $form = $("#"+btnId).closest("form");
$form.find("input").not(".search_onblur").keyup(function(){
searchTriger(btnId);
});
$form.find("input.search_onblur").blur(function(){
searchTriger(btnId);
});
$form.find("input[type=checkbox]").change(function(){
searchTriger(btnId);
});
$form.find("select").change(function(){
searchTriger(btnId);
});
}
function searchTriger(btnId){
if(timeout != null){
clearTimeout(timeout);
}
timeout = setTimeout("searchBtnClick('"+btnId+"')",500);
}
function searchBtnClick(btnId){
$("#"+btnId).click();
}

复制代码 代码如下:

var hideTimeout;
function showLayerMask(){
$layerMask = $(".layerMask");
if($layerMask.length == 0){
var div = "";
var width = document.body.clientWidth;
var Height = document.body.scrollHeight;
var img = "<img src='"+resourcePath+"/src/images/loading2.gif' />";
div += "<div class='layerMask' style='width:100%;height:" + Height + "px;'>";
div += img;
div += "</div>";
var $body = $("body");
$body.prepend(div);
}
$layerMask.show();
//1分钟后取消
hideTimeout = setTimeout(hideLayerMask,60000);
}
function hideLayerMask(){
if(hideTimeout != null){
clearTimeout(hideTimeout);
}
$layerMask = $(".layerMask");
$layerMask.hide();
}

复制代码 代码如下:

var emailTime = 30;
function nextCanDo(){
$("#mailValidateCodeBtn").val(emailTime+"秒");
emailTime -= 1;
if(emailTime ==0 ){
$("#mailValidateCodeBtn").val("重新获取验证码");
$("#mailValidateCodeBtn").attr("disabled",false);
emailTime = 30;
}else{
setTimeout("nextCanDo()",1000);
}
}
