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>
2.使用js加载
<a href="#" id="tBox" title="这是一个提示信息">Hover me</a><script> $(function () { $("#tBox").tooltip(); })</script>
二、属性
1.position:消息框位置(left,right,top,默认bottom)
<a href="#" id="tBox" title="这是一个提示信息">Hover me</a><script> $(function () { $("#tBox").tooltip(); })</script>
2.content:消息框内容,可以是html
<a href="#" id="tBox" title="这是一个提示信息">Hover me</a><script> $(function () { $("#tBox").tooltip({ content: "<strong>我是html</strong>" }); })</script>
3.trackMouse:为true时,允许提示框跟鼠标移动
<a href="#" id="tBox" title="这是一个提示信息">Hover me</a><script> $(function () { $("#tBox").tooltip({ trackMouse: true }); })</script>
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>
2.onUpdate:在提示框内容更新时触发,默认content为null
<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>
4.onDestroy:在提示框被撤销的时候触发
<a href="#" id="tBox" title="这是一个提示信息">Hover me</a><script> $(function () { $("#tBox").tooltip({ onDestroy: function (none) { alert("提示框被销毁"); } }); $("#tBox").click(function () { $(this).tooltip("destroy"); }); })</script>
四、方法
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>
5.reposition:重置提示框位置
<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>
