Sorry I know this place is mainly for C. But I don't really want to have to register to another site for this JS question. (I'm sure a lot of you have dealt with websites anyway)
This question is pretty simple, but I just can't figure out why the FOR loop breaks. To me it seems like a bug. It simply breaks after 1 iteration.
I created a dummie page, for you to see. Simply save it as a .html and run it
The error occurs on fields[i].value .. The error is the var iCode:<html><head><script type="text/javascript"> function validateForm() { var fields = new Array; var fields =[ document.getElementById("one"), document.getElementById("two"), document.getElementById("three")]; for (var i = 0; i < parseInt(fields.length); i++) { alert(i); if ( fields[i].value == "" ) { alert("Field" + (i+1) + " has no value"); } } } </script></head><body> <form name="form1"> Field 1 enter: <input type="text" id="one"> <br /> Field 2 enter: <input type="text" name="two"> <br /> Field 3 etner: <input type="text" name="three"> <br /><br /> <input type="button" onclick="validateForm()" value="Submit" /> </form></body></html>
You see, if you replace i with 0: fields[0].value, it will successfully loop 3 times.
I just don't understand why using that variable, fails?
I tried so many things, moving the script to bottom of page, converting value of i to a char, etc. I may of missed something, but if you take a quick look maybe you know this problem. (I know I can resort to doing multiple IF statement, I just want to know why this logical loop doesn't work)
