This time I will bring you JS implementation of timer + prompt box. What are the precautions for JS implementation of timer + prompt box. The following is a practical case, let's take a look.
Business scenario: When the mouse moves into an element, a prompt box is displayed for introduction. It will disappear automatically when the mouse is removed. Introduce ToolTip.js and ToolTip.css
Main method: ToolTip.show (id of the element to be prompted, as long as it is not repeated, html text to be prompted, width (optional), height (optional) );
ToolTip.show(obj, id, html, width, height);
The effect is as follows:
1. Display text:
2: Display pictures
3: Display website
js code: F :\Html5\Plugins\ToolTip\js\ToolTip.js
(function () { var ToolTip = {}; /** * 显示函数 */ ToolTip._showTip = function (parentId, childId, html, width, height) { var parent = document.getElementById(parentId)//要提示的元素 var child = document.getElementById(childId); if (child === null) {//创建 var toolTip = document.createElement("p"); toolTip.classList = "ui-tooltip-box"; toolTip.id = childId; toolTip.innerHTML = html; parent.appendChild(toolTip); toolTip.style.width = width ? width + "px" : "auto" toolTip.style.height = height ? height + "px" : "auto" //定位: toolTip.style.position = "absolute"; toolTip.style.display = "block"; var left = parent.offsetLeft; var top = parent.offsetTop; if (left + toolTip.offsetWidth > document.body.clientWidth) { left = document.body.clientWidth / 2; } toolTip.style.left = left + "px"; toolTip.style.top = top + 20 + "px"; parent.onmouseleave = function (ev) { setTimeout(function () { //延迟: document.getElementById(childId).style.display = "none";//隐藏 }, 300); } } else { //显示 document.getElementById(childId).style.display = "block"; } }, /** * 调用入口 */ ToolTip.show = function (parentId, childId, html, width, height) { var parent = document.getElementById(obj) parent.onmouseenter = function (ev) { ToolTip._showTip(parentId, childId, html, width, height) } } window.ToolTip = ToolTip; })();//为防止污染,将方法写在匿名函数中
html code: F:\Html5\Plugins\ToolTip\ToolTip.html
<!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <title>提示框</title> <link rel="stylesheet" type="text/css" href="ToolTip.css" rel="external nofollow" > </head> <body> <p class="ui-tooltip-demo"> <p><a class="ui-tooltip" id="tooltip-text">唐诗</a></p> <p><a class="ui-tooltip" id="tooltip-photo">背景图片</a></p> <p><a class="ui-tooltip" id="tooltip-poem">Yi人诗社</a></p> </p> <script src="js/ToolTip.js"></script> <script> //调用方式 ToolTip.show("tooltip-text", "01", "唐诗泛指创作于唐朝的诗" + "。唐诗是中华民族最珍贵的文化遗产之一,是" + "中华文化宝库中的一颗明珠," + "同时也对世界上许多民族和国家的文化发展产生了很大影响," + "对于后人研究唐代的政治、民情、风俗、" + "文化等都有重要的参考意义和价值。",300,90); ToolTip.show("tooltip-photo", "02", "<img src=\"imgs/bg.jpg\" height=\"80px\">",150,80); var html='<iframe src="http://www.toly.top" width="480px" height="300px"/>' ToolTip.show("tooltip-poem", "03", html); </script> </body> </html>
css code: F:\Html5\ Plugins\ToolTip\ToolTip.css
body { font-size: 14px; line-height: 1.8; background-image: url("imgs/bg.jpg"); } .ui-tooltip-demo { width: 500px; margin: 30px auto; padding: 20px 30px; background-color: rgba(100%, 100%, 100%, 0.4); border-radius: 10px; text-align: center; box-shadow: 2px 1px 0px 3px rgba(0, 0, 0, 0.2); } .ui-tooltip-demo .ui-tooltip { color: #03f; font-size: 18px; cursor: help; } .ui-tooltip-box { display: block; background: #fff; line-height: 1.6; border: 1px solid #6cf; color: #333; padding: 20px; font-size: 12px; border-radius: 5px; overflow: auto; }
