EasyUI系列学习(六)-Tooltip(提示框)_html/css_WEB-ITnose
一、创建组件
0.Tooltip不依赖其他组件
1.使用class加载
<a href="#" class="easyui-tooltip" title="这是一个提示信息">Hover me</a>

4.deltaX,deltaY:提示框具体左上角的位置
<a href="#" id="tBox" title="这是一个提示信息">Hover me</a><script> $(function () { $("#tBox").tooltip({ deltaX: 50, deltaY:50 }); })</script>
5.showDelay,hideDelay延时多少毫秒显示/隐藏提示框,默认是200
<a href="#" id="tBox" title="这是一个提示信息">Hover me</a><script> $(function () { $("#tBox").tooltip({ showDelay: 1000, hideDelay: 2000 }); })</script>
6.showEvent,hideEvent:激活显示/隐藏事件时候的提示框,默认为mouseenter,mouseleave
<a href="#" id="tBox" title="这是一个提示信息">Hover me</a><script> $(function () { $("#tBox").tooltip({ //鼠标单击是显示提示框 showEvent: "click", //鼠标双击是隐藏提示框 hideEvent: "dblclick" }); })</script>
三、事件
1.onShow,onHide:在显示/隐藏提示框的时候触发
<a href="#" id="tBox" title="这是一个提示信息">Hover me</a><script> $(function () { $("#tBox").tooltip({ onShow: function (e) { alert("显示提示框的触发"); }, onHide: function (e) { alert("隐藏提示框的触发"); } }); })</script>

<a href="#" id="tBox" title="这是一个提示信息">Hover me</a><script> $(function () { $("#tBox").tooltip({ content: "这是新内容", onUpdate: function (content) { alert("内容被更新:" + content); } }); })</script>
3.onPosition:在提示框位置被改变的时候触发
<a href="#" id="tBox" title="这是一个提示信息">Hover me</a><script> $(function () { $("#tBox").tooltip({ onPosition: function (left, top) { console.log("left:" + left + ",top:" + top); } }); })</script>

1.options:返回属性对象
2.show,hide:显示/隐藏提示框
<a href="#" id="tBox" title="这是一个提示信息">Hover me</a><script> $(function () { $("#tBox").tooltip({ }); $("#tBox").tooltip("show"); $("#tBox").tooltip("hide"); })</script>
3.update:更新content的内容
<a href="#" id="tBox" title="这是一个提示信息">Hover me</a><script> $(function () { $("#tBox").tooltip({ }); //鼠标移动到”Hover me“时触发 $("#tBox").tooltip("update", "更新的内容"); })</script>
4.tip:返回tip元素对象;arraw返回箭头元素对象(实际就是提示框生成的两个div)
<a href="#" id="tBox" title="这是一个提示信息">Hover me</a><script> $(function () { $("#tBox").tooltip({ onShow: function () { //div.tooltip.tooltip-bottom console.log($("#tBox").tooltip("tip")); //div.tooltip.tooltip-outer,div.tooltip-arrow console.log($("#tBox").tooltip("arrow")); } }); })</script>

<a href="#" id="tBox" title="这是一个提示信息">Hover me</a><script> $(function () { $("#tBox").tooltip({ onShow: function () { $(".tooltip-bottom").css("left", 500); }, onHide: function () { $("#tBox").tooltip("reposition"); } }); })</script>

HTML defines the web structure, CSS is responsible for style and layout, and JavaScript gives dynamic interaction. The three perform their duties in web development and jointly build a colorful website.

HTML, CSS and JavaScript are the three pillars of web development. 1. HTML defines the web page structure and uses tags such as, etc. 2. CSS controls the web page style, using selectors and attributes such as color, font-size, etc. 3. JavaScript realizes dynamic effects and interaction, through event monitoring and DOM operations.

The roles of HTML, CSS and JavaScript in web development are: 1. HTML defines the web page structure, 2. CSS controls the web page style, and 3. JavaScript adds dynamic behavior. Together, they build the framework, aesthetics and interactivity of modern websites.

The future of HTML is full of infinite possibilities. 1) New features and standards will include more semantic tags and the popularity of WebComponents. 2) The web design trend will continue to develop towards responsive and accessible design. 3) Performance optimization will improve the user experience through responsive image loading and lazy loading technologies.

The future trends of HTML are semantics and web components, the future trends of CSS are CSS-in-JS and CSSHoudini, and the future trends of JavaScript are WebAssembly and Serverless. 1. HTML semantics improve accessibility and SEO effects, and Web components improve development efficiency, but attention should be paid to browser compatibility. 2. CSS-in-JS enhances style management flexibility but may increase file size. CSSHoudini allows direct operation of CSS rendering. 3.WebAssembly optimizes browser application performance but has a steep learning curve, and Serverless simplifies development but requires optimization of cold start problems.

The roles of HTML, CSS and JavaScript in web development are: HTML is responsible for content structure, CSS is responsible for style, and JavaScript is responsible for dynamic behavior. 1. HTML defines the web page structure and content through tags to ensure semantics. 2. CSS controls the web page style through selectors and attributes to make it beautiful and easy to read. 3. JavaScript controls web page behavior through scripts to achieve dynamic and interactive functions.

HTML is the cornerstone of building web page structure. 1. HTML defines the content structure and semantics, and uses, etc. tags. 2. Provide semantic markers, such as, etc., to improve SEO effect. 3. To realize user interaction through tags, pay attention to form verification. 4. Use advanced elements such as, combined with JavaScript to achieve dynamic effects. 5. Common errors include unclosed labels and unquoted attribute values, and verification tools are required. 6. Optimization strategies include reducing HTTP requests, compressing HTML, using semantic tags, etc.
