[RESOLVED] disabling form inputs

Copy linkTweet thisAlerts:
Sep 02.2008

hi experts,

i have a form where a user can either enter a filename into a [B]input type=”text”[/B] (if the user already uploaded the file via ftp), or he can select a file via [B]input type=”file”[/B] to upload the file via the form.

to avoid conflict i want to disable either the textfield or the file field once there´s something entered into the other, all in realtime and before the submit button is pressed.

any ideas on how to approach this?

thanks in advance,
jogol

<input type="text" name="textFilename" onchange="document.form1['fileFilename'].disabled=true;">
<input type="file" name="fileFilename" onchange="document.form1['textFilename'].disabled=true;" enctype="multipart/form-data">
</form>

is there a workaround in case the user enters a value into the text field but deletes it again? the way it is now the file field doesnt become active again then.

@FangSep 02.2008 — Fx won't let you change the file input back to it's original state. IE does allow this.<form action="#" name="form1">
<input type="text" name="textFilename" onchange="if(this.value!=defaultValue){document.form1['fileFilename'].disabled=true;}else{document.form1['fileFilename'].disabled=false;}">
<input type="file" name="fileFilename" onchange="if(this.value!=defaultValue){document.form1['textFilename'].disabled=true;}else{document.form1['textFilename'].disabled=false;}" enctype="multipart/form-data">
</form>
