I want to find any <!-- --> comment tags in a page and then read the contents. I would also like to distinguish between those in the body and those elsewhere in the HTML document.What do I use to get an array of these elements?
View 10 RepliesI have a form with a javascript form validator to check against all fields to make sure they are entered in correctly and to reduce spam. I am using
Code:
var allowedChars = /^[a-zs]+$/i;
to specify that I only want characters and so on. Is there a way to reverse that to say this html input field CAN NOT contain any of the following? I want to check against a comment box to make sure no url address is entered (http:www.) because most spam contains urls in this field. Is there a simple solution?
I came across some embedded JavaScript code and I noticed some weird “HTML comment-like tags” within embedded JavaScript that are getting rendered in FireFox but not IE. Specifically the closing tag "//--> And the JavaScript code between these tags is functional (not commented out)!

I need to make a javascript that when I am at a page within a game I play and click the javascript, it will get the value of a table cell, separate them to x and y variables and then put the values into a link that opens. The open link is of a php script that uses $_GET for the values of the variables to query my database.I am terrible at javascript and have been trying to do this for 2 days now with no success.Here's the scripts so it is easier to understand:This is part of the html page that is from the game. I need to have the javascript get 432|608 and assign x=432 and y=608 in this case, although those number change, the place in the table that that they are displayed do not change.
<td>Coordinates:</td>
<td><a href="game.php?village=19392&s=map&x=432&y=608">432|608</a></td>

If there are multiple hyperlinks in a webpage, How do I recognize them using java script. Also How do I store the content of the hyperlink in a variable , so that the data stored in the variable will be used the query a database and populate results in another webpage For example there are many links in the webpage like this
<a href="update.php">text 1</a>.
<a href="update.php">text 2</a>
.
.
.
<a href="update.php">text N</a>
User can click any one of the hyperlinks in the webpage. If user clicks on hyperlink 'text4', text4 should be saved in a variable. Then pass the variable value to update.php , where database is queried using the statement "SELECT text4 from table sometable" and results are populated.

View 14 Replies View RelatedI can read the contents of an iframe:
HTML Code:
var iframe = document.getElementById("message");
var iframeContents = iframe.contentDocument.body.innerHTML;
var txtarea = document.getElementById('message2');
txtarea.value = iframeContents;
This will read the contents of an iframe, and write it to a textarea.
iframe is editable, and content is entered by the user. Still, this works.
But, below code is not working. Trying to put some content to an iframe, with the same innerHTML method above. It returns no errors or warnings. Even last alert() displays "<div>lorem ipsum</div>", but iframe is empty, it displays nothing..
HTML Code:
var textContent = "lorem ipsum";
var iframe2 = document.getElementById('message');
iframe2.contentDocument.body.innerHTML = '<div>'+textContent+'</div>'
alert(iframe.contentDocument.body.innerHTML);

So can someone gimme any reference that i can refer to? example and solution aso can so i can get an idea on it.
If you give an element an inline property, as in
<div id='testDiv' style='display:block'>blah</div>
then an alert(document.getElementById('testDiv').style.display) will of course give you "block." But, if you give the element a property through an external CSS file, the same alert comes up empty!
This is causing me big problems as I've discovered and is ridiculous. Can javascript read properties from external CSS sheets?
