Changing the parameters of a Javascript function using GreaseMonkey
- by Dave
There are a lot of questions here about Greasemonkey, but I didn't see anything directly related to my question.
I'm on a website that uses a text editor control, and it's really annoying that they don't allow horizontal resizing (only vertical). So if you are using a cheapo projector that only supports 1024x768, the text runs off of the screen and there's nothing you can do about it.
I looked at the page source, and found the section of code that I want Greasemonkey to modify:
<script type="text/javascript">
// TinyMCE instance type: CD_TinyMCE
tinyMCE.init({
convert_urls : "",
mode : "specific_textareas",
editor_selector : "rte",
theme : "advanced",
theme_advanced_toolbar_location : "top",
theme_advanced_toolbar_align : "left",
theme_advanced_statusbar_location : "bottom",
theme_advanced_resizing : true,
**theme_advanced_resize_horizontal : false**,
...
I just want to change the boldfaced value to true. I tried to approach this the brute force way and replace the text this way:
function allowHorizontalResize() {
var search_string = "theme_advanced_resize_horizontal : false";
var replace_string = "theme_advanced_resize_horizontal : true";
var doc_text = document.body.innerHTML;
document.body.innerHTML = doc_text.replace( search_string, replace_string);
}
...but it doesn't work. However, I know the basic search and replace part works because I can use this script to replace text within the editor -- I just can't change the javascript code that initializes the text editor.
Can someone explain what I'm doing wrong? Is this even possible?
