This javascript code can be used on your client to strip out unwanted characters from a field. To use you would add - onChange="this.value=JRestrict(this.value)" - into your HTML <input> tag The function would go in the HEAD of the HTML document. function JRestrict(fldVal) { var charsToAllow='ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz '; var fldVal2=''; for (i=0 ; i < fldVal.length ; i+=1) { if (charsToAllow.indexOf(fldVal.charAt(i))!=-1) { fldVal2+=fldVal.charAt(i) } } return fldVal2; } ----- Original Message ----- From: Pedro Silva <psilva@ruido-visual.pt> To: Zope - Questions <zope@zope.org> Sent: Friday, February 18, 2000 11:21 AM Subject: [Zope] Forcing Hi, How can I force a field to just have a value type? Example: the name field will just receive letters, it can'r receive numbers. Can anyone tell me how can I do this? Another thing. Do anyone knows where I can get information about Tiny Tables? I already searched in www.zope.org, www.egroups.com, and www.google.com, but I couldn't get anything. Please send you answers to: psilva@ruido-visual.pt Thanks, Pedro _______________________________________________ Zope maillist - Zope@zope.org http://lists.zope.org/mailman/listinfo/zope ** No cross posts or HTML encoding! ** (Related lists - http://lists.zope.org/mailman/listinfo/zope-announce http://lists.zope.org/mailman/listinfo/zope-dev )
