bootstrap弹出层的多种触发方式
bootstrap弹出层有多种触发方式，以下是我用到的几种方式：
1.方法一：button中属性触发
注意：button中的data-target内容应该和要和弹出层中的id保持一致
data-target=”#mymodal-data”——–
id=”mymodal-data”
<!--在button上绑定触发弹出层的属性-->
<button
class="btn
btn-primary
delete"
data-toggle="modal"
data-target="#mymodal-data"
data-whatever="@mdo">
修改
</button>
<!--

-->
<div
class="modal"
id="mymodal-data"
tabindex="-1"
role="dialog"
aria-labelledby="mySmallModalLabel"
aria-hidden="true">
<div
class="modal-dialog">
<div
class="modal-content">
<div
class="modal-header">
<button
type="button"
class="close"
data-dismiss="modal">
<span
aria-hidden="true">×</span>
<span
class="sr-only">Close</span>
</button>
<h4
class="modal-title">弹出层标题</h4>
</div>
<div
class="modal-body">
<p>弹出层主体内容</p>
</div>
<div
class="modal-footer">
<button
type="button"
class="btn
btn-default"
data-dismiss="modal">关闭</button>
<button
type="button"
class="btn
btn-primary">保存</button>
</div>
</div>
</div>
</div>
结果：
2.方法二：通过js绑定
注意：将button的id和弹出层的id分别赋给
$m_btn和$modal，当$m_btn被点击后$modal弹出。
<button
class="btn
btn-info"
type="button"
id="y-modalBtnAdd"
>
<label
>添加</label></button>

<div
class="modal"
id="y-myModalAdd"
tabindex="-1"
role="dialog"
aria-labelledby="mySmallModalLabel"
aria-hidden="true">
<div
class="modal-dialog">
<div
class="modal-content">
<div
class="modal-header">
<button
type="button"
class="close"
data-dismiss="modal">
<span
aria-hidden="true">×</span>
<span
class="sr-only">Close</span>
</button>
<h4
class="modal-title">弹出层标题</h4>
</div>
<div
class="modal-body">
<p>通过js绑定button和弹出层触发</p>
</div>
<div
class="modal-footer">
<button
type="button"
class="btn
btn-default"
data-dismiss="modal">关闭</button>
<button
type="button"
class="btn
btn-primary">保存</button>
</div>
</div>
</div>
</div>
<!--js代码-->
<script
type="text/javascript">
$(function(){
//
dom加载完毕
var
$m_btn
=
$('#y-modalBtnAdd');
//y-modalBtnAdd是button的id
var
$modal
=
$('#y-myModalAdd');
//y-myModalAdd是弹出的遮罩层的id，通过这两个id进行绑定
$m_btn.on('click',
function(){
$modal.modal({backdrop:
'static'});
});
});
</script>
结果：
3.方法三：点击表格一行，弹出弹出层
动态给tr标签加弹出的触发属性
<!--表格-->
<table
class="table
table-bordered
"
style="width:
400px">
<thead>
<tr>
<th>一</th>
<th>二</th>
<th>三</th>
</tr>
</thead>
<tbody
class="tableBody">
<tr>
<td>one</td>
<td>two</td>
<td>three</td>
</tr>
<tr>
<td>four</td>
<td>five</td>
<td>six</td>
</tr>
</tbody>
</table>
<!--

-->
<div
class="modal"
id="mymodal-data"
tabindex="-1"
role="dialog"
aria-labelledby="mySmallModalLabel"
aria-hidden="true">
<div
class="modal-dialog">
<div
class="modal-content">
<div
class="modal-header">
<button
type="button"
class="close"
data-dismiss="modal">
<span
aria-hidden="true">×</span>
<span
class="sr-only">Close</span>
</button>
<h4
class="modal-title">弹出层标题</h4>
</div>
<div
class="modal-body">
<p>点击表格一行内容，弹出弹出层</p>
</div>
<div
class="modal-footer">
<button
type="button"
class="btn
btn-default"
data-dismiss="modal">关闭</button>
<button
type="button"
class="btn
btn-primary">保存</button>
</div>
</div>
</div>
</div>
<!--js代码-->
<script
type="text/javascript">
$(function
()
{
$(".tableBody>tr").each(function
()
{
$(this).on("click",function
()
{
$(this).attr({"data-toggle":"modal","data-target":"#mymodal-data","data-whatever":"@mdo"});
})
});
});
</script>
结果：
bootstrap的弹出层在整个屏幕的上半部分，可以将它居中显示。（方法二可以让弹出层居中显示）
$(function(){
//
dom加载完毕
var
$m_btn
=
$('#y-modalBtnAdd');
y-modalBtnAdd是button的id
var
$modal
=
$('#y-myModalAdd');
y-myModalAdd是弹出的遮罩层的id，通过这两个id进行绑定
//
测试
bootstrap
居中
，bootstrap的弹出层默认是左右居中，上下则是偏上，此代码将弹出层上下也居中了，但是会抖
动一下
$modal.on('shown.bs.modal',
function(){
var
$this
=
$(this);
var
$modal_dialog
=
$this.find('.modal-dialog');
var
m_top
=
(
$(document).height()
-
$modal_dialog.height()
)/2;
$modal_dialog.css({'margin':
m_top
+
'px
auto'});
});
});
</script>
