如何通過<a href tag

Question

In the above JSP i am trying to pass the text box value through href tag. I came across the above syntax in stackoverflow. But it does not seem to be working. Need help.

HTML

<input id="orderedItems" type="text" name="orderedItems" value="hiii" /> 
<a href='products.jsp?id=1&loginid=${userName}&orderim='+ document.getElementById('orderedItems').value;> 

Answer 1

You should change the href attribute in the onchange event of the input.

Example

var link = document.getElementById("link"), 
    txt = document.getElementById("txt"), 
    baseUrl = link.href; 

txt.onchange = function() { 
    link.href = baseUrl + "?param=" + this.value; 
};
