How can I write the contents of a variable into the text area of a <td>here</td> with javascript?
How can I write the contents of a variable into the text area of a <td>here</td> with javascript? I would like to prompt the user using the called function onclick and store what they type into a variable and then write the string saved to that variable into the same <TD> that the form/input/prompt function call is in.
I'm thinking that this can be done by accessing the column via the class attribute. Ideally, I'd like the function(s) to be independent and robust such that I can use them for several different columns based on the class attributes.
<html>
<head>
<link href="style.css" rel="stylesheet" type="text/css">
<title>asdfsadf</title>开发者_运维百科;
</head>
<body bgcolor="#000088">
<script type="text/javascript">
function editDates()
{
var dates = prompt("Fill in date(s) of absence",
"Example: Travel 1/7 - 2/10");
document.write.
}
</script>
<table class="mainTable" cellspacing="0" border="1"
cellpadding="1" width="100%" height="100%">
<tr>
<td>name</td><td class="r1c1">
<form method="link" action="index.html" onClick="editDates();">
<input type="button" name="submit" value="Edit"/></form>
</td></tr></body></html>
document.getElementsByClassName('yourClass')[0].innerHTML = 'the content';
I'd recommend using jQuery though, much more beginner friendly / less error prone. In that case it would be:
$('td.yourClass').html('the content');
Install mootools, then check out this jsfiddle.net example I have created for you. Any button element (or any element for that matter) you add the class name of "edit_button" to will then change the contents of it's parent table cell to the response from the users prompt input.
