Bootstrap Modal Plugin
Modal box (Modal) is a child form covering the parent form
1. Basic use
- Through the data attribute : set the attribute data-toggle="modal" on the controller element , and set data-target="#identifier" to control which modal box is operated.
<button class="btn btn-primary btn-lg" data-toggle="modal" data-target="#myModal">
打开模态框
</button>
- Via JavaScript : Using this technique, a modal box with id="identifier" can be called with a simple line of JavaScript:
// 点击提交更改的同时关闭模态框
function handleSubmit() {
$('#myModal').modal('hide')
}
Example:
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
