How to know whether or not a element exist on page

ziscloud

Hi All,

I try to use this code to verify whether a element exist on the page:

if (_condition(_link($label) != null)) {
_click(_radio(0, _near(_link($label))));
} else {
_click(_cell(0, _near(_cell($label))));
}
}

Some times it is work fine, but some times even there is a link element, it also clicks the cell element!

I have used the sahi controller to verity _assertExists(_link("xxxx")), it return true, but in the script

_condition(_link($label) != null)

return false and click the cell element.

is it a bug of sahi, please verify!

If this check is done just after a particular page is loaded, try and add an assertion before this condition to make sure that you have moved to the correct page before it verifies this condition. You can also add a wait, but an assertion is better.

Thanks a lot for your reply!

are you mean the code should like this:

_assertExists(_link($label)); or _wait(10000);

if (_condition(_link($label) != null)) {
_click(_radio(0, _near(_link($label))));
} else {
_click(_cell(0, _near(_cell($label))));
}
}

_wait(10000,_link($label));
This will wait till given amout of time or provided link was found. whichever occurs first. Assert is much better in your case.

Infact, since you do not know if the link will exist or not, assert for something else which will ensure that you are on the right page before you check for your link existence.

This should work:

if(_assertExists(_link("clickme"))){
_alert("it exists on the page");
}

Sorry, this is how to fix the above example, which does work:
if(_condition(_assertExists(_link("clickme")))){
_alert("it exists on the page");
}

This is the best, not adding an "assertion" in the test logs:

if(_condition(_link("clickme"))){
_alert("it exists on the page");
}
