JS implementation stays in the interface prompt box
This time I will bring you JS implementation to stay in the interface prompt box. What are the precautions for JS implementation to stay in the interface 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 automatically disappear 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
