问题:
我有一个确认框,每当我单击保存按钮时,都会弹出该确认框。单击“确定”后,它可以很好地保存数据。但是,当我单击“取消”时,它不会取消更改。而是保存它们。您能帮我解决这个问题吗?
这是它的JavaScript:
/
<asp:Button ID="view_btn_save" Text="Save" ValidationGroup="view" OnClick="view_btn_save_click"
OnClientClick="Validate_view()" runat="server"
/>
</td>
<script type="text/javascript">
function Validate_view() {
var value = document.getElementById('<%=view_txt_name.ClientID%>').value;
var value2 = document.getElementById('<%=view_txt_title.ClientID%>').value;
var value3 = document.getElementById('<%=view_txt_description.ClientID%>').value;
var value4 = document.getElementById('<%=view_txt_pixelwidth.ClientID%>').value;
var value5 = document.getElementById('<%=view_txt_pixelheight.ClientID%>').value;
if (value == '' || value2 == '' || value3 == '' || value4 == '' || value5 == '') {
return alert('Please enter the missing fields');
}
else {
return confirm('Confirm changes?');
}
}
最佳答案
您需要在OnClientClick
声明中添加return语句:
OnClientClick="return Validate_view();"
在显示警报的情况下,我将代码更改为:
alert("...");
return false;
编辑:这是一个完整的例子
<script type="text/javascript">
function Validate_view() {
var value = document.getElementById('<%=view_txt_name.ClientID%>').value;
var value2 = document.getElementById('<%=view_txt_title.ClientID%>').value;
var value3 = document.getElementById('<%=view_txt_description.ClientID%>').value;
var value4 = document.getElementById('<%=view_txt_pixelwidth.ClientID%>').value;
var value5 = document.getElementById('<%=view_txt_pixelheight.ClientID%>').value;
if (value == '' || value2 == '' || value3 == '' || value4 == '' || value5 == '') {
alert('Please enter the missing fields');
return false;
}
else {
return confirm('Confirm changes?');
}
}
</script>
<asp:Button ID="view_btn_save" runat="server" Text="Save" OnClientClick="return Validate_view()" OnClick="view_btn_save_click" />
