AJAX: manually calling wym.update()

[karlmdavis]

Hello all,

I'm trying to integrate WYMeditor with an Ajax-using application and am having trouble with getting access to the update() method. I have a button that performs an Ajax submit and also has "wymupdate" as its class, but unfortunately the submit code seems to be processed before the wymupdate code.

I have tried adding the following Javascript before my Ajax submit, but it seems to not work:

Code: Select all

for(wym in WYM_INSTANCES) { wym.update(); }

In Venkman, I see it throw an "wym.update is not a function" error.

Due to the framework I'm using, I'm unable to manipulate my Ajax submit code, other than specifying Javascript to be run before or after it. Any ideas how I can fix this problem?

Thanks!
Karl

Well, I guess I'm lacking in my knowledge of Javascript. I still have no idea why the above code doesn't work, but the following does:

Code: Select all

for(i=0;i<WYM_INSTANCES.length;i++) { WYM_INSTANCES[i].update(); };

Hope this helps someone out!

Actually this is the safest way to enumerate an array in JS.

Hi,

When I use this code, it will update the first instance, and then outright end the loop, not updating any of the other instances.

If I try to iterate backwards through the WYM_INSTANCES array like so:

Code: Select all

for(i=WYM_INSTANCES.length - 1; i >= 0; i--)  { WYM_INSTANCES[i].update(); };

it tells me that WYM_INSTANCES[i] has no properties on the first time through the loop.

I've got a test page here. You can see this issue by clicking the "Update test" button at the bottom of the page.

Note that I have another issue as well that is unrelated to this particular issue. I'll post that in another thread that is relevant.

Thanks, I really hope to get this working, this looks like the best editor out there.

I have this history of agonizing over things for days, finally posting a question to a forum, and then figuring it out shortly thereafter.

I didn't explicitly declare the "i" variable, so somewhere in the update function it was getting it confused with its own "i" variable. Declaring it solved the updating problem.
