Using jQuery to add and delete the input box group input-group based on Bootstrap_javascript skills
This article shares an example of using jQuery to implement the adding and deleting operations of the input box group input-group for your reference. The specific content is as follows
Note that this requires the use of the input box group of the Bootstrap framework, such as:
<div class="row">
<div class="col-lg-6">
<div class="input-group">
<span class="input-group-addon">
<input type="checkbox" aria-label="...">
</span>
<input type="text" class="form-control" aria-label="...">
</div><!-- /input-group -->
</div><!-- /.col-lg-6 -->
<div class="col-lg-6">
<div class="input-group">
<span class="input-group-addon">
<input type="radio" aria-label="...">
</span>
<input type="text" class="form-control" aria-label="...">
</div><!-- /input-group -->
</div><!-- /.col-lg-6 -->
</div><!-- /.row -->
Rendering of Demo case:
Here provides the self-made plug-in inputGroup.js
The parameter can set whether the middle control in the input box group is a text field or an input box; and set the content of the operation on the right side of the input box group.
To use inputGroup.js, just add a selector in the corresponding container, such as a div, then use jQuery to obtain the jQuery object corresponding to the selector, and call the initInputGroup method.
inputGroup.js
/**
* Created by DreamBoy on 2016/4/29.
*/
$(function() {
$.fn.initInputGroup = function (options) {
//1.Settings 初始化设置
var c = $.extend({
'widget' : 'input',
'add' : "<span class=\"glyphicon glyphicon-plus\"></span>",
'del' : "<span class=\"glyphicon glyphicon-minus\"></span>"
}, options);
var _this = $(this);
//添加序号为1的输入框组
addInputGroup(1);
/**
* 添加序号为order的输入框组
* @param order 输入框组的序号
*/
function addInputGroup(order) {
//1.创建输入框组
var inputGroup = $("<div class='input-group' style='margin: 10px 0'></div>");
//2.输入框组的序号
var inputGroupAddon1 = $("<span class='input-group-addon'></span>");
//3.设置输入框组的序号
inputGroupAddon1.html(" " + order + " ");
//4.创建输入框组中的输入控件（input或textarea）
var widget = '', inputGroupAddon2;
if(c.widget == 'textarea') {
widget = $("<textarea class='form-control' style='resize: vertical;'></textarea>");
inputGroupAddon2 = $("<span class='input-group-addon'></span>");
} else if(c.widget == 'input') {
widget = $("<input class='form-control' type='text'/>");
inputGroupAddon2 = $("<span class='input-group-btn'></span>");
}
//5.创建输入框组中最后面的操作按钮
var addBtn = $("<button class='btn btn-default' type='button'>" + c.add + "</button>");
addBtn.appendTo(inputGroupAddon2).on('click', function() {
//6.响应删除和添加操作按钮事件
if($(this).html() == c.del) {
$(this).parents('.input-group').remove();
} else if($(this).html() == c.add) {
$(this).html(c.del);
addInputGroup(order+1);
}
//7.重新排序输入框组的序号
resort();
});
inputGroup.append(inputGroupAddon1).append(widget).append(inputGroupAddon2);
_this.append(inputGroup);
}
function resort() {
var child = _this.children();
$.each(child, function(i) {
$(this).find(".input-group-addon").eq(0).html(' ' + (i + 1) + ' ');
});
}
}
});
Demo case——InputGroupDemo
The directory structure is as follows:
index.html
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta http-equiv="X-UA-Compatible" content="IE=edge">
<meta name="viewport" content="width=device-width, initial-scale=1">
<title>输入框组</title>
<link rel="stylesheet" href="css/bootstrap.min.css" type="text/css">
<style>
/*.input-group-add .input-group {
margin: 10px 0;
}*/
</style>
<!--<link href="assets/font-awesome/css/font-awesome.css" rel="stylesheet" />-->
<!--[if lt IE 9]>
<script src="js/html5shiv.js"></script>
<script src="js/respond.min.js"></script>
<![endif]-->
</head>
<body>
<div class="container">
<div class="input-group-add">
<!--<div class="input-group">
<span class="input-group-addon"> 1 </span>
<!–<input type="text" class="form-control" aria-label="...">–>
<textarea class="form-control"></textarea>
<span class="input-group-addon">
<button class="btn btn-default" type="button"> + </button>
</span>
</div>-->
</div>
</div>
<script src="js/jquery-1.11.1.min.js"></script>
<script src="js/bootstrap.min.js"></script>
<script src="inputGroup.js"></script>
<script>
$(function() {
$('.input-group-add').initInputGroup({
'widget' : 'textarea', //输入框组中间的空间类型
/*'add' : '添加',
'del' : '删除'*/
});
});
</script>
</body>
</html>
If the middle control in the input box group requires input, you can set:
$('.input-group-add').initInputGroup({
'widget' : 'input', //输入框组中间的空间类型
/*'add' : '添加',
'del' : '删除'*/
});
Or do not set it, because the default middle control is input.
The effect of the middle control being input is as follows:
