使用JQuery更新span标记值
使用JQuery更新span标记值
提问于 2009-04-09 18:21:24
我正在尝试更新一个位于字段集标签中的span标签，该标签位于一个图例标签中。这个想法是在选择组件时更新软件项目的成本。如果我只有一个软件项目(例如- Visual Studio 2008 Pro $2800)，下面的代码可以很好地工作，但如果我在另一个字段集中添加第二个项目，那么当我试图更新该字段集的跨度时，它会更新包含Visual Studio软件的字段集的跨度。你知道我做错了什么吗？
<script language="javascript" type="text/javascript">
$(document).ready(function() {
$("li").click(function() {
var itemCost = 0;
$("legend").each(function() {
var SoftwareItem = $(this).text();
itemCost = GetItemCost(SoftwareItem);
$("input:checked").each(function() {
var Component = $(this).next("label").text();
itemCost += GetItemCost(Component);
});
$("#ItemCostSpan").text("Item Cost = $ " + itemCost);
});
function GetItemCost(text) {
var start = 0;
start = text.lastIndexOf("$");
var textCost = text.substring(start + 1);
var itemCost = parseFloat(textCost);
return itemCost;
}
});
});
</script>
