JavaScript Code for filtering Non Numeric Value

CODE:


function filterNonNumeric(field) {
var result = new String();
var numbers = "0123456789";
var chars = field.value.split(""); // create array
for (i = 0; i < value =" result;">

......The above code filter the non numeric value .........i.e, when ever user enter the value other than numeric it wont allow you to enter it accepts only the numeric value
.....the input for the above java script function is property/ name from the Textbox in Jsp

for ex..from jsp (please ignore the starting symbol(--) in tag


<--input type=text name="units">

the above name units is given to that function.
having doubt on this .......leave .....a..comment
Thanks

Make Textbox hidden/visible based on the DropDown selection using JavaScript

SOLUTION:

the following function will help you to solve this ......


function hideTextBox(dropDown1){
var valFromDropDown = dropDown1.value;
if(valFromDropDown == 'WRITE'){
document.forms[0].textBox1.style.visibility = "";
} else{
document.forms[0].textBox1.style.visibility = "hidden";
}
}

in the above example hideTextBox is the function name .....
and the input for this function is dropDown value selected......
in this example we are hiding the the text box if the drop down value is 'WRITE' else it will show the textbox......



the following Example.jsp page will clearly explain you how to implement this and please ignore this Symobl(--)inside the every tag Starting. i put this (--) for displaying html tags only kindly ignore that symbol

Example.jsp(please ignore this(--)symbol and try it it will surely work

from the above Example.jsp you can clearly understood how the function is implemented

note:

you have to declare these property in the form bean this is the example used in struts Frame work.

if you still having doubts write a comment on this.
