Unable to validate input data in array

vikas251074

I am using ASP
In my company, all employees have to sent materials out of premises. Any employee who need to sent material out will use this web application. In the first page, an employee enters firm name, vehicle no, driver name, purpose, persons taking out, received by, remarks. In the second page, employee enters no. of materials to be taken out. In the third page, displays no. of rows for entry of material details like material name, serial_no., qty, weight remarks.
I have written validation for all field. All validation works well. In the third page, validation works well when no. of material taken out is 1. When it is > 1, then no validation works.

Please suggest me, what to do?

I am giving you code for entry and validation.

Thanks and regards,
Vikas

It looks like the validation is actually being done in the javascript, not the ASP. I'll move this to the javascript forum.

Instead of the ASP code, can you please post the html code only, the one you get in view source? Post only the HTML part then, not the JavaScript. JS is already clear.

Yes Sir. Here is my HTML code without JavaScript. I am eagerly waiting for your suggestion.

Here line no. 21 to 29 is under loop using ASP code which has been removed.
If 1 material is taken out then loop will run 1 times. Here validation works.
If 2 material is taken out then loop will run 2 dtimes. Validation not works for > 1.
Line no. 23, 24, 25, 26 and 28 is using validation function which was built using JavaScript.

Ok, the problem is, when you refer an element as
var str=document.my form.mat.value, it just assumes the first (or may be last, not sure) element in the form with this name.
So, it works only when there's one entry.
When more then one entries, it doesn't work.

For this, make reference as
Expand|Select|Wrap|Line Numbers
  1. var str = document.getElementsByName('mat');
  2. for (var i=0; i<str.length; i++) {
  3.     do_validation_for(str[i]);
  4. }
Hope you understand this.. :)

And instead of the function check, check1, check2, you can reduce that code into one line by using regExp.

I have written following function as per your suggestion. And this function is called in input tag of material name i.e. 23rd line of HTML code (without ASP code) posted here just above. But still it is not working. What wrong am I doing?

Thanks and regards,
Vikas

Expand|Select|Wrap|Line Numbers
  1. function checkmat()
  2. {
  3.   var t;
  4.   var str = new RegExp("\\w","i")
  5.   str = document.getElementsByName('mat');
  6.   if (str.length > 0)
  7.   {
  8.     for (var i=0; i<str.length; i++) 
  9.     {

Oh, so you are calling this function onblur event?

Need to do a little modification then.
Expand|Select|Wrap|Line Numbers
  1. function checkmat(mat) {
  2.     if (mat.value=="") {
  3.         alert("Material must be entered");
  4.         mat.focus();
  5.         return;
  6.     }
  7.     else if (!mat.value.test(/^[\w\s]*$/i)) {
  8.         alert("Special characters are not allowed.");
  9.         mat.focus();
  10.         return;
  11.     }
  12.     return;
  13. }
And write checkmat(this) instead of checkmat().

Very very nice sir,
It is working now.
Now the validation message is displaying 'Material must be entered.' It is very good. Now the problem in this function is -
1) Else part is not working.
2) But it got into repeated message when clicks on second material row without entering first material. And it never comes out.

I have to use Ctrl+Alt+C to close the browser. Is there any idea to avoid this? Can I avoid user to go to second row without entering first row?

Thanks and regards,
Vikas

It shouldn't. There's some other problem in the code.

Is there any idea to avoid this? Can I avoid user to go to second row without entering first row?
That can be done, but you don't really need that. There's some other problem in the code as I said.

Also, make all the validation functions in the code similar to the material validation one.

vikas251074

OK Sir,

But the problem lies in this part, because when user clicks on second material row which is blank and the first being blank, then it gives the message for both, When I clicks on OK for 'Material must be entered' then it gives message for second row, when I clicks on OK for 'Material must be entered' then it gives message for first row. This process repeats for forever. And now Ctlr+Alt+C to close the browser.

What should I do?

Thanks and regards,
Vikas
