A reusable javascript function to assign a value to a control.

I'm looking for a solution and I thought a client side javascript function  will work. This function will assign the text or title value of a tab  to a particular control.

A function is always "re-usable", that's the purpose we make a piece of codes as a function.

it depends on the functionality what you intend to include.

I guess what you mean is to get the Page Title and put it into a Form field? if yes, you can try:
<html>
<title>whatever ...</title>
<body onload="setText(document.forms[0].Text1)">
<form>
<input id="Text1" type="text" />
</form>
</body>
</html>

<script type="text/javascript">
    function setText(c) {
        c.value = document.title;
    }
</script>

The idea of the script is correct .

10:<script type="text/javascript">
11:    function setText(c) {
12:        c.value = document.title;
13:    }
14:</script>

How would I assign the c.value to a control in MasterPage?

Yes , ASP.NET.
The child page has tabs like this
 <ul class="tabs" id="thistab" runat="server">

                <li class="tab-link current" data-tab="tab-1" id="tab11" data-toggle="tab"><a href="#Person">Personal Information</a></li>

                <li class="tab-link" data-tab="tab-6" id="tab16"><a href="#Info" data-toggle="tab"  title="Employee Information">Employee Information</a></li>
                <li class="tab-link" data-tab="tab-2" id="tab12"><a href="#Assign" data-toggle="tab" title="Assignment History">Assignment History</a></li>

Open in new window


Those title will be assign to a  label control in Masterpage when click.

ok, let's say in your MasterPage you got this label control named Label1.

<asp:Label ID="Label1" runat="server" Text="Label" ClientIDMode="Static"></asp:Label>

Open in new window

(make sure ClientIDMode = "Static")

then to change this in child page, you can try:

<ul class="tabs" id="thistab" runat="server">

                <li class="tab-link current" data-tab="tab-1" id="tab11" data-toggle="tab"><a href="#Person" onclick="return setText('Label1',this.text);">Personal Information</a></li>

                <li class="tab-link" data-tab="tab-6" id="tab16"><a href="#Info" data-toggle="tab" title="Employee Information" onclick="return setText('Label1',this.text);">Employee Information</a></li>
                <li class="tab-link" data-tab="tab-2" id="tab12"><a href="#Assign" data-toggle="tab" title="Assignment History" onclick="return setText('Label1',this.text);">Assignment History</a></li>
        </ul>

Open in new window


then your javascript function will look like this:

<script type="text/javascript">
    function setText(c, v) {
        document.getElementById(c).innerHTML = v;
        return true;
    }
</script>

Open in new window

I think the change is working for the label in the masterpage. I only change text to title attribute. But what if I want to append the value of the current Label1
for example: the current value of Label1 is  'Home/Person 'and I would like to append the the title so it becomes

'Home/Person/Personal Information'  - That is my current location now based on what I clicked.
