Infinte loop with onblur

BBDan · Jul 22, 2003

Hi guys, wondering if any of you know how to break an infinite loop caused by an onblur event?

<HTML>
<HEAD>
<TITLE>Webpurchase</title>
<SCRIPT LANGUAGE="JavaScript">
<!--

function checkCo()
{
if(document.form1.companyName.value=="&quot

{
window.alert("Please enter Company Name.&quot

document.form1.companyName.focus()
return false
}
return true
}

function checkPerson()
{
if(document.form1.contactPerson.value=="&quot

{
window.alert("Please enter Contact Person.&quot

document.form1.contactPerson.focus()
return false
}
return true
}

//-->
</script>
</head>
<BODY>

<FORM ACTION="webpurchase3.php"
ID="form1"
NAME="form1"
METHOD="POST"
// onsubmit="return checkData()"
// onblur="checkCo()"
// onblur="checkPerson()"
>

<tr>
<td>Company Name</td>
<td align=left><INPUT TYPE="TEXT" ID="companyName" size=30 maxlength=30 onblur="checkCo()"></td>
</tr>

<tr>
<td>Contact Person</td>
<td align=left><input type="text" name="contactPerson" size=30 maxlength=30 onblur="checkPerson()"></td>
</tr>

Hi vbkris,

Thanks for your help. It breaks the loop, but it doesn't check my other form fields. Do you have any suggestions?

Thanks!

try this:
<FORM ACTION="webpurchase3.php"
ID="form1"
NAME="form1"
METHOD="POST"
onsubmit="return checkData()"

>

Hi,

It still doesn't work, but I am now writing a whole new check sequence. Do you know, by any chance, how to check each form field one by one rather than using "onsubmit"

Thanks

onMouseOut, onMouseOver, onChange, onClick, etc.

that can be done but validation for all fields must be the same.....

i always check the fields one by one....

atleast does the function checkData() get called in my previous code?

If you have a form where you want to validate some, or all, of the fields, create a "validate" function and put all of your tests in that function.

function validateForm(theForm) {

if (theForm.companyName.value.length == 0) {
alert("Please Enter A Company Name&quot

;
theForm.companyName.focus()
return (false);}

if (theForm.address.value.length == 0) {
alert("Please Enter Company Address&quot

;
theForm.address.focus()
return (false);}
.
.
.
}

In your <FORM> tag, call it like this: onSubmit="return validateForm(this)...

This way, you can pick and choose what to test, and with what values. All tests must be false before the form will submit.

There's always a better way. The fun is trying to find it!

Hi vbkris,

The checkdata() works with onsubmit; i guess what i am stuck with is the individual checks, so i use onblur after every entry box.

<tr>
<td>Company Name</td>
<td align=left><INPUT TYPE="TEXT" ID="companyName" name= "companyName" size=30 maxlength=30 onblur="JavaScript:checkAccess() " ></td>
</tr>

<tr>
<td>Contact Person</td>
<td align=left><input type="text" ID="contactPerson" name="contactPerson" size=30 maxlength=30 onblur="JavaScript:checkAccess()" ></td>
</tr>

Well, now the loop is reiterating 2 times for some reason, but i guess i need to debug it myself. Thanks for your help.
