findElement error handling?

[mavdi]

How would I go about clicking a button if it exists and ignoring it if it doesn't?

this.ptor.findElement(this.by.linkText('/logout'))
     .then(function(element) {
      element.click().then(callback);
     })

isElementPresent won't do it for me, because I want to handle a case where the element is not present. Almost like

this.ptor.isElementNotPresent(someElement).then(callback);

Any sort of error handling on the promise? Any other way of doing this?

Error handler is within the then function:

this.ptor.findElement(this.by.linkText('/logout'))
     .then(function(element) {
      element.click().then(callback);
     }
     , function() {
          callback()
     });

I wish everyone just agreed on how to do promises.

I tried below code and it still it failing if element not found on the page,
ptor.findElement(protractor.By.xpath('//*[@id="dLabel"]')).then(function(element) {
element.click().then(callback);
}
, function() {
callback()
});

Use Try Catch block. Try the below code:
browser.driver.findElement(by.id(browser.params.loginPage.IdTextBoxCode)).then(function(codeTextBox)
{
try
{
console.log("Entering Code: "+code);
codeTextBox.sendKeys(code);
}
catch(err) {
console.log('In catch block');
}
}, function(err) {
console.info('Code Text Box not displayed on page. Proceeding with default Code');
});
