Length of String

[Asiralia]

i have a question. I have an input field and want to insure that the user doesn't forget about the leading zeros when he searches by an agent #.

The only way I thought is to check the lenght of what the user input...

Any suggestions???

FieldName.value.length should contain what you're after.

Thank you for your suggestion. I have put the following in the code and it is not working...

<script language="JavaScript">
function validate() {
if (document.form1.control.value.length <8) {
alert("Please check the control # you have entered.");
return false;
}</script>


<div align="right"><b>Agent Number</b></div>
</td>
<td>
<input type="text" name="agt" align="right" size="8" maxlength="8" value=" " tabindex="8" class="textNumber" onsubmit="validate()">

Try substituting 'agt' for 'control':


<script language="JavaScript">
function validate() {
if (document.form1.agt.value.length <8) {
alert("Please check the control # you have entered.");
return false;
}
}
</script>

...
<div align="right">
<b>Agent Number</b></div>
</td>
<td>
<form name="form1">
<input type="text" name="agt" align="right" size="8" maxlength="8" value=" " tabindex="8" class="textNumber" onsubmit="validate()">

Asiralia,

Looks like the problem with your example is your missing
the closing brace of your "if" statement.

Thank you so much.

I actually need a minor adjustment it is possible for the input field to have no value...

For the JavaScript to give an error only if they put something in the field that is less than 8 characters...

In "bears" sample simply extend the "if" clause to test for...


if ((document.form1.agt.value.length > 0) ||
(document.form1.agt.value.length < 8)) {
alert("Your error statement code here");
return(false);
}

Sorry - change the OR to an AND (&&) test (ouch)...
