Asp image button having dynamic attributes

Question

0.00/5 (No votes)

See more:

Creating dynamic textbox with "-" on the right (aspx image button)

this portion

RemoveA(this,' + value + ');

returns

RemoveA(this,&#39; + value + &#39;)

in my debug mode.

Neccessary to push in the value, so as know which textbox is removed etc. Because of this, my website experience Page Validation issue.

 function GetDynamicFm(value) {
        var string1 = '<input name = "txtA' + value + '" id = "txtA' + value + '"  type="text" value = "" size="25" /> <asp:ImageButton ID="btnMinTextBox1" runat="server" ImageAlign="AbsMiddle" AutoPostBack="False" ImageUrl="../../img/minus_icon.png" onClientClick="RemoveA(this,' + value + ');return false;" ToolTip="Remove"/><input name = "hiddenAId' + value + '" id= "hiddenAId' + value + '" type="hidden" value=""/><input name = "hiddentxtA' + value + '" id="hiddentxtA' + value + '" type="hidden"/>';
}

What I have tried:

I tried a lot of ways. Sometime experienced "the server not well formed"

There is no point of creating dynamic asp controls from javascript since the controls are processed from the server and rendered as html element in the browser page, The javascript is not aware of the asp prefix to the elements created. so replace the asp elements with the html element as

function GetDynamicFm(value) {
         var string1 = '<input name = "txtA' + value + '" id = "txtA' + value + '"  type="text" value = "" size="25" /> <img src="../../img/minus_icon.png" onclick="RemoveA(this,"' + value + '");return false;" title="Remove"/><input name = "hiddenAId' + value + '" id= "hiddenAId' + value + '" type="hidden" value=""/><input name = "hiddentxtA' + value + '" id="hiddentxtA' + value + '" type="hidden"/>';
         return string1;
     }

     var a = GetDynamicFm('-');

RemoveA(this,' + value + ') - this code will work only when a number is passed to the function, if there is any string then it will throw an error for invalid argument, so better pass it as string in all cases and use it accordingly

onclick="RemoveA(this,"' + value + '");
