Accessing struts Bean property in javascript

[p hasini]

1. I have a textbox called amt which has a validation to accept only numbers with one decimal point.
2. I use struts tags for the textbox and javascript to perform the validation
3. Struts code:

<td cellvalue='<bean:write name="amount" property="amt"/>' onkeypress="return isNumberKey(event)">

4. Javascript code:

function isNumberKey(evt)
{
 var charCode = (evt.which) ? evt.which : event.keyCode
 if (charCode != 46 && charCode > 31 && (charCode < 48 || charCode > 57))
 return false;
 return true;
}

5. The above validation works for numbers but I have to put a validation for only one decimal point.
6. I want to use the folowing approach:
Use a regular expression like

/^\d+(\.\d+)?$/

But how do I call the bean property in javascript and match the value with the regular expression.
For HTML textbox,I can use

document.getElementById.value.match(/^\d+(\.\d+)?$/),

but how does it work in struts.
7. Is there any other approach.


Please help me resolve this.

Hi Hasini,
Once after reaching Client, it is no more struts and its just HTML. Since you need onfly validation, you can try using getting the element by name. It should be available in the document. Additionally, you can include the same in reg exp in validation.xml for form submission.
