使用Bootstrap
<form id="search" action="" method="post" >
<div class="dropdown">
<button data-toggle="dropdown" id="dropdownMenu1" type="button" class="btn btn-default dropdown-toggle">Fixed <span class="caret"></span></button>
<ul aria-labelledby="dropdownMenu1" role="menu" class="dropdown-menu">
<li role="presentation"><a href="#" tabindex="-1" role="menuitem">Florida</a></li>
<li role="presentation"><a href="#" tabindex="-1" role="menuitem">Texas</a></li>
<li role="presentation"><a href="#" tabindex="-1" role="menuitem">Washington</a></li>
<li role="presentation"><a href="#" tabindex="-1" role="menuitem">New York</a></li>
<li role="presentation"><a href="#" tabindex="-1" role="menuitem">Ohio</a></li>
</ul>
</div>
</form>
jQuery保持选择下拉选项
var jQee = jQuery.noConflict();
jQee(".dropdown-menu li").click(function(){
var selText = jQee(this).text();
jQee(this).parents('.dropdown').find('.dropdown-toggle').html(selText+' <span class="caret"></span>');
//jQee('#search').submit();
});
HTML下拉列表
<select onchange="form.submit()" name="template">
<option value="F" selected="true">Florida</option>
<option value="T">Texas</option>
<option value="W">Washington</option>
<option value="N">New York</option>
<option value="O">Ohio</option>
</select>
对于上面的下拉菜单,我根据用户选择提取option value
。
使用Bootstrap
执行此操作时,我可以保留下拉值selected
,但当我将其与PHP
一起使用时,我还需要{{1}中的值}}变量,以便执行$_POST
查询并根据从下拉列表中选择的值显示结果。
我怎样才能实现它?

使用隐藏字段并在用户选择状态时填充它。
HTML
<form id="search" action="" method="post" >
<input type="hidden" name="selection">
<div class="dropdown">
<button data-toggle="dropdown" id="dropdownMenu1" type="button" class="btn btn-default dropdown-toggle">Fixed <span class="caret"></span></button>
<ul aria-labelledby="dropdownMenu1" role="menu" class="dropdown-menu">
<li role="presentation"><a href="#" tabindex="-1" role="menuitem">Florida</a></li>
<li role="presentation"><a href="#" tabindex="-1" role="menuitem">Texas</a></li>
<li role="presentation"><a href="#" tabindex="-1" role="menuitem">Washington</a></li>
<li role="presentation"><a href="#" tabindex="-1" role="menuitem">New York</a></li>
<li role="presentation"><a href="#" tabindex="-1" role="menuitem">Ohio</a></li>
</ul>
</div>
</form>
的JavaScript
$(document).ready(function() {
$("ul li a").click(function() {
text = $(this).closest("li").text();
$("input[name='selection']").val(text);
$(this).parents('.dropdown').find('.dropdown-toggle').html(text+' <span class="caret"></span>');
$("#search").submit();
});
});
See jsfiddle使用inspect元素检查隐藏字段的值。
