HTML select tag value does not immediately change after calling a function from script
Date : March 29 2020, 07:55 AM
Does that help you have to save the current select state during the function. Here is a small adaption (see commented lines) <script language="javascript" type="text/javascript">
function createNewSelectTag()
{
/*check if 2nd select tag is already exist. if it is, cannot make another 2nd select tag*/
if (document.getElementById('createdSelectTag'))
{
if (document.getElementById('SelectTag1').selectedIndex == 0)
{
var element = document.getElementById('createdSelectTag');
element.parentNode.removeChild(element);
}
}
else
{
// save selected state
var holdState = document.getElementById('SelectTag1').selectedIndex;
if (holdState > 0)
{
var newSelectTag = '<li id="createdSelectTag"><span>2nd Select Tag :</span>' +
'<select id="SelectTag2">' +
'<option value="a">A</option>' +
'<option value="b">B</option>' +
'<option value="c">C</option>' +
'</select>' +
'</li>';
document.getElementById('MAIN').innerHTML += newSelectTag;
// set to saved state
document.getElementById('SelectTag1').selectedIndex = holdState;
}
}
}
</script>

Calling a function on a HTML check box change without submission using C#
Date : March 29 2020, 07:55 AM
hope this fix your issue You can do this with C# in code behind. Add a OnCheckedChanged event to the CheckBox and set the AutoPostBack to true and handle the change. Note that a Panel becomes a div in HTML. <asp:CheckBox ID="limitOptions" runat="server" OnCheckedChanged="limitOptions_CheckedChanged" AutoPostBack="true" />
<asp:Panel ID="locationOptions" runat="server" Visible="false">
Radius (KM) <asp:TextBox ID="radius" runat="server" Text="100"></asp:TextBox>
</asp:Panel>
<asp:CheckBox ID="limitOptions" runat="server" onclick="toggleOptions()" />
<div id="locationOptions" runat="server" style="display: none">
Radius (KM)<asp:TextBox ID="radius" runat="server" Text="100"></asp:TextBox>
</div>
<script type="text/javascript">
function toggleOptions() {
var id = '#<% =locationOptions.ClientID %>';
if ($(id).css('display') == 'none') {
$(id).slideDown('fast', function () { });
} else {
$(id).slideUp('fast', function () { });
}
}
</script>

python function calling with dict - calling a function which has parameters but not listing the parameter explicitly
Date : March 29 2020, 07:55 AM
this one helps. You are partially correct, you need to pass a parameter. Look at this line items = sorted(word_count.items(), key=get_count, reverse=True)
items = sorted(word_count.items(), key=lambda x: -x[1])

Calling javascript Function from HTML with multiple parameters
Date : September 25 2020, 12:00 PM
Any of those help I'm trying to call a javascript function called confirmRemove(title, id) to remove an element from a table. This function should be called when the user clicks on a link that looks like an "X". I attached my code below to show how I went about doing this, but I'm seeming to be having some errors and I'm not sure why. Most of the elements are able to be removed, but for a few when I click the link to call the function, nothing happens. Is there a better way of doing this? Not sure why this would happen. , You can try this code <td> <a onclick="confirmRemove('<?php echo $title; ?>','<?php echo $id; ?>')"
href="javascript:void(0)">X</a></td>
