How do I get checkbox element identifier generated dynamically?

Hi,
Could you please tell me how do I recognize a checkbox which is present inside a div tag. And the checkbox ID is changing dynamically everytime when we hit the page and the element also does not have a name attribute.

In the "firepath" plug-in, it is displaying like ".//*[@id='ext-gen780']" but it is not reliable.

I have tried with XPath command with contains() function as below

Command : ClickAt
Target : xpath=.//*[contains(text(),'Custom2')]

It is finding the correct element [ when no text is present in the page, contains "Custom" ]. If it is there means, the actual checkbox is not checked.

I'm struggling with this issue for TWO days. Please help me to solve this.

Here's the HTML content for a checkbox gathered by using Firebug Addon.

Please find the screenshot for your reference.



Thanks in advance

Even the ID is dynamically generated, there should be a pattern. Identify the pattern and try the code below.

WebElement checkboxElement = .findelement(By.xpath("//*[@type='checkbox' and contains(@id, 'COMMON_PATTERN')]")

Yeh! Agree with you.

I'm getting element ID thru' FirePath plugin like this.

.//*[@id='ext-gen780']

the common pattern is for all the element is, "ext-gen" (with some numbers). As per your reply, how can I determine this is what the particular element?

Note:

Either by value attribute of the checkbox or the element text.
