Let's say I have this piece of code from first.html
<input type="text" id="name">
<a href="second.html">Go to next page</a>
How can I make it that when you go to second.html, javascript alerts the value of [name] from first.html OR the html adds an h1 tag with the value of [name] from first.html
you could use onclick function on anchor tag.
<input type="text" id="name">
<a onclick="goToNextPage()">Go to next page</a>
<script>
function goToNextPage()
{
var value = document.getElementById('name').value;
window.location.href="second.html?name="+value;
}
</script>
Or you could use form.submit() to post the form values to request.
As HTML is only markup language, not programming language. So, you would need either php/ javascript to fetch that value on second page.
function qs(search_for) {
var query = window.location.search.substring(1);
var parms = query.split('&');
for (var i=0; i<parms.length; i++) {
var pos = parms[i].indexOf('=');
if (pos > 0 && search_for == parms[i].substring(0,pos)) {
return parms[i].substring(pos+1);;
}
}
return "";
}
and then call that function in your second page as.
<script type="text/javascript">
document.write(qs("name"));
</script>
You can use document.getElementById() function to get input and access it's value property to read what was entered there.
The onclick attribute on your anchor element will execute a custom function which will take the href property of the anchor and append the url-encoded value of the input field.
Then it will go to that new URL.
The return false ensures that built-in href event does not execute.
function link(anchor) {
var name = document.getElementById("name").value
var url = anchor.href + "?name=" + encodeURIComponent(name);
window.location.href = url;
}<input type="text" id="name">
<a href="second.html" onclick="link(this); return false;">Go to next page</a>To read the passed in variable on the receiving page, use the technique described in this SO post:
