Hello Professionals,

I am making an application using asp.net-mvc with C#.
There are many pages (views as per MVC) and every page have few textboxes.

I want to apply trim function to all the textboxes.
One single and inappropriate solution is to go to every page and apply jquery's trim function to each and every textbox.

It would be of great help to me if anyone can suggest me a better way and efficient way.

Regards,
Shivang.

Why? What seems to be a problem? Why you did not solve it so far? Any difficulty, in particular?

Problem:
Initially trim function was not applied but now I want to apply it due to some constraints.
Its cumbersome to go to each and every textbox and apply trim(). So I just wanted to know if there is any generic functionality that can be applied as a whole , where I don't need to go to each and every textbox. :-)

Not clear. If you really want to trim each and every text box (why, by the way), this is what you should do. Why cumbersome? Do you want all text boxes to trim themselves? Well, instruct them to do so. :-)

What's the problem? As if you never heard of recursion and loops.

Looking for some "generic functionality" is wrong way of thinking. Have a problem? Solve it with your own hands. And you did not even explain what's your problem. Act be definition. Is there something you don't know? Or you need more bravery?

Hello Shivang,

You should be doing this on server side (It's part of business validations) rather than relying on it happening on client side.

If you any way want it you can write a single javascript function to enumerate all forms and all controls within it and apply trim to all values in txtbox, textarea. You can then call this function before submitting the form.

for (var fCntr = 0; fCntr < document.forms.length; fCntr++) {
var val = null,
var frm = document.forms[fCntr];
for (eCntr = 0; eCntr < frm.elements.length; eCntr++) {
val = null;
var elm = frm.elements[eCntr];
var stagName = elm.tagName;
if (stagName === 'INPUT')
{
if (elm.hasAttribute('type')
{
var typ = elm.getAttribute('type');
if (typ != null && (typ.toUpperCase() == 'TEXT' || typ.toUpperCase() == 'PASSWORD'))
val = elm.value;
}
}
else if (stagName == 'TEXTAREA')
val = el.value;
if (val != null)
elm.value = val.replace(/^\s+|\s+$/g,"");
}
}

Hi,

You could extend the textbox control to give you trim funcionality when you request the textbox value.

Find all textboxes in your project and replace with your new textbox control.

Good idea +5....I am wondering why microsoft does not have inbuilt the Trim() in the Text property itself...

José Amílcar Casimiro 19-Mar-13 18:11pm

thank you

ShivangDesai 20-Mar-13 0:44am

It would have been great if Microsoft provided Trim().. ;-)

bbirajdar 20-Mar-13 2:46am

Yes. There should be a default trim() inside the text property itself. So that we can have a alternative NoTrim() when not required..... I guess not more then one in more then ten thousand cases

My 5 too ... sometimes the simplest ideas really are the best
