A coworker wanted to change the width of a textarea on a new-form. This is, as it turns out, not so easy.
The textarea is a complex component, containing lots of other components:
TD
-span
– span
-textarea
– table
-iframe
– div
-iframe
– head
– body
– input
Guess which one you need to change to get/set the width for the multiline textfield? You are thinking about the input field or the textarea? Wrong, it is the body field of the iframe inside the div.
So, to make a long story short..if you want to change the width:
$('iframe[title="Rich Text Editor"]').width('400');
This will set the width of all Rich-Text-Editors on the page. If you only want to change 1, you have to take the ID of the iframe and put it there:
$('iframe[id="ctl00_m_g_52db519f_2c86_4899_ad40_66394be45805_ctl00_ctl05_ctl04_ctl00_ctl00_ctl04_ctl00_ctl00_TextField_iframe"]'). width('400');
Same thing for the height of a richt text:
$('iframe[title="Rich Text Editor"]').height('400');
