以下是示例代码..如果我注释掉脚本,它将在按钮单击时调用服务器端功能。以下代码中的错误是什么?
<form id="form1" runat="server">
<input type="checkbox" id="chb1" value="Hourly" />
<input type="checkbox" id="chb2" value="Daily" />
<input type="checkbox" id="chb3" value="Weekly" />
<input type="checkbox" id="chb4" value="Monthly" />
<input type="checkbox" id="chb5" value="Yearly" />
<asp:Button Text="submit" runat="server" ID="btnSubmit" OnClick="btnSubmit_Click"/>
</form>
<div></div>
<script src="https://code.jquery.com/jquery-1.10.2.js"></script>
<script type="text/javascript">
var selectedcout = 0;
var countChecked = function () {
var n = $("input:checked").length;
$("div").text(n + (n === 1 ? "is" : "are") + "checked");
};
countChecked();
$("input[type=checkbox]").on("click", countChecked);
</script>
答案 0 :(得分:0)
您需要挂钩表单的submit
事件,而不是提交按钮的click
,以便您可以停止提交表单。试试这个:
var selectedcout = 0;
var countChecked = function() {
var n = $("input:checked").length;
$("div").text(n + (n === 1 ? " is " : " are ") + "checked");
};
countChecked();
$('#form1').on('submit', function(e) {
e.preventDefault(); // stop the form submitting
countChecked();
});
