Get value of Span Text
JavascriptHtmlJavascript Problem Overview
I have a span with class="span"
and a hidden field class="dropdown"
.
The span
text changes, and I need to grab the text and set it as the value of the hidden field's value.
I will then use php (I already have) and use the name of the hidden field to email me the text.
How do I do it?

Solution 3 - Javascript
The accepted answer is close... but no cigar!
Use textContent
instead of innerHTML
if you strictly want a string to be returned to you.
innerHTML
can have the side effect of giving you a node element if there's other dom elements in there. textContent
will guard against this possibility.
Solution 4 - Javascript
You need to change your code as below:
<html>
<body>
<span id="span_Id">Click the button to display the content.</span>
<button onclick="displayDate()">Click Me</button>
<script>
function displayDate() {
var span_Text = document.getElementById("span_Id").innerText;
alert (span_Text);
}
</script>
</body>
</html>

Judging by your other post: https://stackoverflow.com/questions/10343376/how-to-get-the-inner-text-of-a-span-in-php. You're quite new to web programming, and need to learn about the differences between code on the client (JavaScript) and code on the server (PHP).
As for the correct approach to grabbing the span text from the client I recommend Johns answer.
These are a good place to get started.

Also I recommend using jQuery (Once you've got some JavaScript practice) it will eliminate most of the cross-browser compatability issues that you're going to have. But don't use it as a crutch to learn on, it's good to understand JavaScript too. http://jquery.com/
