Hi I would like a dynamic JS function to run, based on the content of a Dynamic Field, it shows a Div in a HTML field, and hides the others. At the moment they are all staying hidden until I click on the field that changes them. I would like the JS to run, based on the fields value at load of page. How to tell JS which field it is dynamically? Thanks C

Hi Craig, try going to JS function under Module Configuration / Javascript / Custom Javascript File and place it in the Initial Javascript. That way, the JS function will run on page load. See if this works for you. -- David

Hi David, The issue is the dynamic field ID. If I put function test($(ShortFieldName_FieldID) { } will that work?? I don't think so. I need to dynamically tell it the field ID, or hard code it in?? C

HI Craig, check out some of the functions under Custom Javascript file. If you place your functions there, you should be able to use a variable name. Then you call the function passing the $(ShortFieldName_FieldID) token value in the initial page load. -- David

Ok, so as suspected, the funtion doesn't appear to work. ShortFieldName = AccountType Mind, the JS is not erroring, so I would suspect it is using the standard $function which is document.getElementById( ??? How do I tell the function to run, and tell it the ASPX ClientID of AccountType? ------------------js extract------------- //onload function to run shHTML($(AccountType_FieldID)); function shHTML(varAcTypeID) { var vC1 = $('Consumer1'); var vC2 = $('Consumer2'); var vB1 = $('Biz1'); var vB2 = $('Biz2'); var vB3 = $('Biz3'); var AcType = $(varAcTypeID); var vP = $('Promo'); showhtml(vP.id); //Handle Changed Account Type switch (AcType.options[AcType.selectedIndex].value) { case 'Consumer - Free': showhtml(vC1.id); hidehtml(vC2.id); hidehtml(vB1.id); hidehtml(vB2.id); hidehtml(vB3.id); break; case 'Consumer - Full Registered': showhtml(vC2.id); hidehtml(vC1.id); hidehtml(vB1.id); hidehtml(vB2.id); hidehtml(vB3.id); break; case 'Business - Standard': showhtml(vB1.id); hidehtml(vC2.id); hidehtml(vC1.id); hidehtml(vB2.id); hidehtml(vB3.id); break; case 'Business - Gold': showhtml(vB2.id); hidehtml(vC2.id); hidehtml(vB1.id); hidehtml(vC1.id); hidehtml(vB3.id); break; case 'Business - Platinium': showhtml(vB3.id); hidehtml(vC2.id); hidehtml(vB1.id); hidehtml(vB2.id); hidehtml(vC1.id); break; default: break; } //end Switch } //end ShowHideHTML

just had a thought, that maybe you meant I could create another field, with a client event, onload, but this is not on of the available keywords for the events.

Hi Craig, at page load, what is the actual field value of AccountType? Is there a default value? Also, if you use Firefox, can you download and install Firebug to trace through the javascript code and see what value it is actually seeing, if any? -- David
