                </a>
            </spam>
        </div>
     </div>

I want to get this text if you can see it in DOM Pur. Requisition No. Acc000056Zip created successfully

I have tried fetching the text and store it in a var

var str = "";
 str = element(by.id('#lblSuccessMessage')).getAttribute('value');

and also this:

var str = "";
str = element(by.id('#lblSuccessMessage')).getText().then(function(text){
console.log(text);
return text;
});

Actually I am making a purchase requistion and there is alert which generates the Purchase requistition no but it contains Pr. no but surrounded with texts for that I am applying regEx and it says str.match() is not a function.

For regEx I have tried this

prno = str.match(/ Pur. Requisition No. Acc(\d+)/i)[0]; 

Answer 1

Okay I got solution for this:

var str = $('#lblSuccessMessage').getText().then(function(text){
        console.log(text); 
        var r = /\d+/;
        console.log((text.match(r)[0]));
        prno = text.match(r)[0];
        //prno = str.match(/ Pur. Requisition No. Acc(\d+)/i)[0];
      });
      //console.log("Purchase requistion no..."+prno);
