I have a drop-down list with 3 values, based on these values, different textareas are shows. I'm getting an error when trying to parse the values. Unable to set property 'value' of undefined or null reference. on inputList.value= '';

This worked in earlier version but not 8.0.08. Here is the relevant JS:

 //Begin function cleanArray
function cleanArray(originalArray){
	var newArray = new Array(); 
	for(var i = 0; i < originalArray.length; i++){
		if(originalArray[i] != ""){
			newArray.push(originalArray[i]); 
		}
	}
	return newArray; 
}
//End function cleanArray
 
 
 
 
//Begin function parseList
function parseList(textArea){
	var textAreaControl = document.getElementById(textArea); 
	var itemArray = textAreaControl.value.split("\n"); 
	var whichInput = ""; 
	switch(textArea){
		case "top_assoc_area":
			whichInput = "top_assoc_list";
			break; 
		case "client_group_area": 
			whichInput = "client_group_list"; 
			break; 
		case "chain_area":
			whichInput = "chain_list"; 
			break; 
		case "mid_list_area":
			whichInput = "mid_list";
			break; 
	}
 
	var finalArray = cleanArray(itemArray); 
 
	var inputList = document.getElementById(whichInput); 	
	inputList.value = ""; 
 
	for(var i = 0; i < finalArray.length; i++){	
		//if(i = 0){
		//	inputList.value = ' "' + finalArray[i] + '" '; 
		//}else{	
		//	inputList.value = inputList.value + 'OR "' + finalArray[i] + '" '; 
		//}	
		if(inputList.value == ""){
			inputList.value = "" + finalArray[i].trim() + "";
		}else {
			inputList.value = inputList.value + "," + finalArray[i].trim() + "";
		}
	}
}
//End function parseList

Hi Suzy,

When you say that your JavaScript worked in earlier versions can you please indicate which version.

What browser are you using? Here is the link to the supported browsers - Web Browser Support for WebFOCUS

This looks more like a javascript issue instead of a webfocus issue. How are you passing text area into the gunction? Can you post that piece of code? Or the whole html? I would try putting an alert into the function to make sure you are getting a value passed for text area in the first place.

Hi Susan

Reference the Textarea with the following code:

alert(IbComposer_getCurrentSelection('textarea1'));


IbComposer_setCurrentSelection('textarea1','New message', false);

That will probably work better for you.

Thanks Barry

Susan, its because your switch(textArea), doesn't have a DEFAULT.. Something is being passed in, that doesn't follow your four CASEs.

Add an alert(textArea) right before the switch. See what is being passed.

Hi Suzy,

In chrome press F12 to bring up developer tools, click on the console tab, refresh the procedure and hit the submit button in your procedure. Everything in the console.log(); will be output to the console tab so you can verify your code including parameters ans objects. You are able to add breakpoints in your script and then hover over the parameters to see what values they are.

All nice debugging techniques.

Hopefully below assists you.
