Recently I am using a JQUERY UI Dialog plug-in, which feels very powerful, but the style setting is troublesome. I finally got it done after two days of research.
To run the plug-in, the required environment is as follows
jquery.ui.all.css is the CSS of the startup style. Open it with firefox to view. The title of the floating layer is as follows,
One-stop solution for all people Tip
In fact, it is a span, so according to this class ui-dialog-title we go to the CSS directory of the official website to find the jquery.ui.dialog.css file and find the classui-dialog-title CSS style.
.ui-dialog .ui-dialog-title { font: 62.5% "Trebuchet MS" , sans-serif;font-weight:bold;float: left; margin: .1em 16px .1em 0; height:15px }
Modify this css to achieve the header style of the floating layer we want.
Header background setting:
.ui-widget-header { border: 1px solid #aaaaaa; background: #cccccc url(images/ui-bg_highlight-soft_75_cccccc_1x100.png) 50% 50% repeat-x; color: #222222; font-weight: bold; }
You can remove the background image and set it as the background color
.ui-widget-header { border: 1px solid #aaaaaa; background-color:red; color: #222222; font-weight: bold; }
About the icon settings of x and lower right corner:
icon.ui-icon { width: 16px; height: 16px; background-image: url(images/ui-icons_222222_256x240.png); }

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。

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。

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")”。

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。

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。

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。
