I have captured 3 values from a datalist template using JavaScript, now I need to append these values into an existing anchor which is:
<a id="link" href='nextpage.aspx?id=<%#Eval("PlateId")%>&pp= #Eval("price")%>'>
I found the way to get the anchor href from JavaScript:
<script language='javascript' type="text/javascript" >
function addLink() {
var anchor = document.getElementById("link");
anchor.href = anchor + "&qty=";}
</script>
But, I can't add the js value after "&qty="
, I have tried adding the value like this:
anchor.href = anchor +"&qty=+Value+"
And with this:
anchor.href = anchor +"&qty='Value' "
I can't put it out of the quotation marks, because it won't display in the anchor.

Reset to default 4anchor.href = anchor + "&qty="
should be
anchor.href = anchor.href + "&qty="
...otherwise you are trying to turn the link element into a string!
Meanwhile, you still need to keep Value
out of the quotation marks, otherwise the final text generated will always be exactly that text: Value
. If Value
is a variable and is not returning the value you expect (an empty or undefined value, for example), then you need to look at the code that declares it and change that.
Dynamically change
<a href=""></a>
href atrribute value (or) You can able to append the existing URL
Tips: 1 - Use the jQuery .attr() Method
$("selector").attr("href", newURL));
Tips: 2 - Use javascript element selector document.getElementById
example:
<a href="test.php" id="test">TEST URL</a>
var redirect_url = document.getElementById('test');
redirect_url.href = "new url";
(or)
document.getElementById('test').href = "newURL";
(or)
using setAttribute() method *Note:broken in IE
redirect_url.setAttribute("href", "new url");
