Code 1:
$(function(){
$(".tooltip").mouseenter(function(e){
This.mytitle=this.title
This.title=""
var a="
$("body").append(a);
$("div").css({
"top": (e.pageY y) "px",
"left": (e.pageX x) "px"
}).show("fast")
}).mouseout(function(){
This.title= this.mytitle;
$("div").remove();
});
})
Learning experience:
Do not append div elements under the p tag, as a large deviation will occur!
turn out to be! There is a difference between this and $("this"), if the above
Rewriting this.title to $("this").attr("title") will cause the following mouseout event to be unable to access the saved title
Code 2:
Quoting css: jqueryui/css/ui-lightness/jquery-ui-1.8.18.custom.css
Quoting js: jqueryui/js/jquery-ui-1.8.18.custom.min.js
<script><br /> $( "#dialog:ui-dialog" ).dialog( "destroy" );<br /> <br /> $( "#dialog-message" ).dialog({<br /> <br /> Height: 120,<br /> width: 220,<br /> modal: true,<br /> buttons: {<br /> "No": function() {<br /> //dosomething<br /> $ (This) .dialog ("close"); <br /> },<br /> "Yes": function() {<br /> //dosomething<br /> $( this ).dialog( "close" );<br /> }<br /> }<br /> });<br /> </script>
Code 3:
Use javascript popup layer component easyDialog
After using easyDialog for a period of time, we summarized some problems encountered during use. Recently, we spent some time to reconstruct and optimize the original code, and added some new functions. The original version was just to realize the basic functions of a simple pop-up layer. From a project perspective, it was about how to quickly complete the project. However, this version is not only about realizing the basic functions, but also considers how to make the pop-up layer better and more efficient. Easily applied to projects.
New features in easyDialog v2.0:
1. Added the default pop-up layer content template. If it is just some simple applications, you don’t need to write the structure of the pop-up layer content, but only need to pass a few simple parameters. The original usage method:
easyDialog.open({
container : 'demoBox'
});
Use the default content template, then the container parameter can be used like this:
easyDialog.open({
container : {
Header: 'Pop-up layer title',
Content: 'Welcome to easyDialog : )',
yesFn : btnFn,
NoFn: true
}
});
The displayed effect is as shown below:
If you want to modify the style of the default content template, you can modify the easydialog.css file in the downloaded document to achieve the style you want.
2. Added a drag-and-drop effect to make the pop-up layer have a better user experience, and the content of the pop-up layer can be customized to easily achieve the drag-and-drop effect.
3. A caching system and a micro-event processing system have been added internally, and the pop-up layer content has also been cached to make the pop-up layer perform better.
In addition, the naming of a parameter was modified. The original isOverlay was changed to overlay, and the ids of each element of the original pop-up layer were also renamed to avoid conflicts as much as possible.
The above 3 types of prompt effects are commonly used by me. You can use them freely according to your own project needs

实现方法:1、用“$("img").delay(毫秒数).fadeOut()”语句,delay()设置延迟秒数;2、用“setTimeout(function(){ $("img").hide(); },毫秒值);”语句,通过定时器来延迟。

修改方法:1、用css()设置新样式,语法“$(元素).css("min-height","新值")”;2、用attr(),通过设置style属性来添加新样式,语法“$(元素).attr("style","min-height:新值")”。

区别:1、axios是一个异步请求框架,用于封装底层的XMLHttpRequest,而jquery是一个JavaScript库,只是顺便封装了dom操作;2、axios是基于承诺对象的,可以用承诺对象中的方法,而jquery不基于承诺对象。

增加元素的方法:1、用append(),语法“$("body").append(新元素)”,可向body内部的末尾处增加元素;2、用prepend(),语法“$("body").prepend(新元素)”,可向body内部的开始处增加元素。

删除方法:1、用empty(),语法“$("div").empty();”,可删除所有子节点和内容;2、用children()和remove(),语法“$("div").children().remove();”,只删除子元素,不删除内容。

在jquery中,apply()方法用于改变this指向,使用另一个对象替换当前对象,是应用某一对象的一个方法,语法为“apply(thisobj,[argarray])”;参数argarray表示的是以数组的形式进行传递。

on()方法有4个参数:1、第一个参数不可省略,规定要从被选元素添加的一个或多个事件或命名空间;2、第二个参数可省略,规定元素的事件处理程序;3、第三个参数可省略,规定传递到函数的额外数据;4、第四个参数可省略,规定当事件发生时运行的函数。

去掉方法:1、用“$(selector).removeAttr("readonly")”语句删除readonly属性;2、用“$(selector).attr("readonly",false)”将readonly属性的值设置为false。
