[英]How to disable a dropdown menu after a button click in jQuery
我有一个包含货币值的下拉菜单,并且新页面加载了所选货币作为URL中的值。 其代码如下:
<div id="procurselect">
<a href="javascript:void(0)" id="chosedCur"><?php echo $curr ; ?></a>
<ul style="display: none;">
<li><a rel="nofollow" title="Euro" onclick="set_currency('http://www.example.com/product.php?pid=<?php echo " $pid " ;?>&cur=EUR');" href="javascript:void(0)" target="_top" rel=nofollow>EUR</a>
</li>
<li><a rel="nofollow" title="Pound Sterling" onclick="set_currency('http://www.example.com/product.php?pid=<?php echo " $pid " ;?>&cur=GBP');" href="javascript:void(0)" target="_top" rel=nofollow>GBP</a>
</li>
<li><a rel="nofollow" title="Canadian Dollar" onclick="set_currency('http:/www.example.com/product.php?pid=<?php echo " $pid " ;?>&cur=CAD');" href="javascript:void(0)" target="_top" rel=nofollow>CAD</a>
</li>
<li><a rel="nofollow" title="Australian Dollar" onclick="set_currency('http://www.example.com/product.php?pid=<?php echo " $pid " ;?>&cur=AUD');" href="javascript:void(0)" target="_top" rel=nofollow>AUD</a>
</li>
........(cont....)
</ul>
</div>
<script>
imitSelect.show({
Target: $('#procurselect'),
Width: 30
});
</script>
我在页面上使用simplecart.js
添加了另一个添加产品按钮。 按钮代码如下:
<a class="item_add" href="javascript:;">
<img src="images/addtocart.png" alt="Add to Cart" width="197" height="58" />
</a>
我希望用户单击addcart按钮后禁用上述货币下拉菜单,以使他无法再次从下拉菜单中更改货币。
我正在使用jQuery。
在jQuery中这怎么可能?
更新:
我需要禁用的选项才能在所有页面上持久保存 ....
提前致谢。
$(document).ready(function(){
$(".item_add").click(function(e){
e.preventDefault();
//jQuery (< 1.7):
//This will disable just the div
$("#procurselect").attr('disabled','disabled');
//OR
//This will disable everything contained in the div
$("#procurselect").children().attr("disabled","disabled");
//jQuery (>= 1.7):
//This will disable just the div
$("#procurselect").prop('disabled',true);
//OR
//This will disable everything contained in the div
$("#procurselect").children().prop('disabled',true);
});
});
请尝试以下操作:
HTML:
<a class="item_add" onclick="disableDropdown()">
<img src="images/addtocart.png" alt="Add to Cart" width="197" height="58">
</a>
JavaScript:
<script>
function disableDropdown(){
$("#procurselect").attr('disabled','disabled');
//or another option
$("#procurselect").css('pointer-events','none'); // this makes it unclickable
//or another option
$("#procurselect").prop( "disabled", true );
}
</script>
$('.item_add').click(function(){
var pro = $('#procurselect ul li');
pro.each(function(){
//Now you have no onlick handler.
this.onclick = null;
/*you can also
this.setAttribute('disabled', true);
*/
});
});
