retain textbox focus

[sriram viswanathan]

What is the best way to retain textbox focus when a validation fails?
Scenario: Txt1 and Txt2 are next to each other. Both are mandatory fields. When we write code in Txt1 onblur, it fires only after yielding focus to Txt2. This causes a problem because, when we do Txt1.focus from onblur, it fires the Txt2 onblur, which in turn requests focus, thus going into a deadlock situation.

To avoid this, had to go for a dirty flag as in the code snippet below.

Is there a better way? Are there any good events that will work in IE as well as Firefox?

Note: Also tried

return false

inside onblur. Dint work.

    
    function setfocus(a_field_id) {
        $(a_field_id).focus()
    }
 
    function onBlur1(){
text1val=document.myform.text1.value;
texterrval=document.myform.texterr.value;
if (texterrval.length==0||texterrval=='false'){
if(text1val.length==0){
alert('text1 null value entered');
//setfocus('text1');
document.myform.texterr.value='true';
document.myform.text1.focus();
 
}else{
//alert('texterrval is true');
document.myform.texterr.value='false';
}
}else{
document.myform.texterr.value='false';
}
}
 
function onBlur2(){
text1val=document.myform.text2.value;
texterrval=document.myform.texterr.value;
if (texterrval.length==0||texterrval=='false'){
if(text1val.length==0){
alert('text2 null value entered');
//setfocus('text1');
document.myform.texterr.value='true';
document.myform.text2.focus();
}else{
alert('texterrval is true');
document.myform.texterr.value='false';
}
}else{
document.myform.texterr.value='false';
}
}
 
  The form is as below:
 form name='myform'>
 input type="hidden" name='texterr' id='texterr'>
 /input>
 input type="text" name='text1' id='text1' onblr='javascript  :-o	  nBlur1()'>
 /input>
 input type="text" name='text2' id='text2' onblr='javascript  :-o	  nBlur2()'>   
 /input>
 /form>

Thanks in advance,
