(Firefox :: General, defect)

Description

[Bart Skondin]

User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.9.0.5) Gecko/2008120122 Firefox/3.0.5
Build Identifier: Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.9.0.5) Gecko/2008120122 Firefox/3.0.5

Linebreaks do not seem to be being counted properly when using javascript length property. Running the following input through the example code below results in different length values when done in IE7 versus Firefox.

Environment: IE7 - 7.0.5730.13
	
	Input Scenario 1:

		1carriageReturnHere
		2

	Result:

		3

	Input Scenario 2:
	
		1carriageReturnHere
		2carriageReturnHere
		3

	Result:
	
		5
		
Environment: Firefox - Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.9.0.5) Gecko/2008120122 Firefox/3.0.5
	
	Input Scenario 1:

		1carriageReturnHere
		2

	Result:
	
		4

	Input Scenario 2:
	
		1carriageReturnHere
		2carriageReturnHere
		3

	Result:
	
		7

Function that displays the scenario:

function callMe(inputField) {

    var inputFieldVal = inputField.value;

    if( inputFieldVal.length > 0 ) {
    	alert('inputFieldVal is ' + inputFieldVal);
    	alert('inputFieldVal.length = ' + inputFieldVal.length);
    }
}

Reproducible: Always

Steps to Reproduce:
1. Enter text with linebreak such as:
 1carriageReturnHere
 2noCarriageReturn

2. Examine length with javascript function.
Actual Results:  
Received a length of 3.

Expected Results:  
I expected a length of 4.

For a quick test to see this bug in action in code other than my own, I used the following site for external validation. Same behavior witnessed.
