Exam 98-382 topic 1 question 6 discussion

document.getElementById("body").innerHTML+=rooms[i] + line.innerHTML

None of the answer given is correct. The correct solution is document.getElementById("para").innerHTML+=rooms[i]+"<br>";

The answer B print this results. Single Double Single Triple Single Double Single Suite Single Double Single Triple Single Double Single The correct answer should be: var line = document.getElementById("para"); var breakLine= document.getElementById("para").innerHTML; var rooms = ["Single", "Double", "Triple", "Suite"]; var i=0; for(i=0;i<rooms.length;i++){ document.getElementById("para").innerHTML += rooms[i] + breakLine; }

Why do you have wrong answers marked, it is very confusing. This one for example- the correct answer is A

None of these answers are correct. document.getElementById("para") returns a reference to the HTML element, not a copy of the current HTML element. This means that innerHTML gets the CURRENT html. The line document.getElementById("para").innerHTML += rooms[i] + line.innerHTML; is equivalent to document.getElementById("para").innerHTML += rooms[i] + document.getElementById("para").innerHTML; In other words, it's: newHTML = currentHTML + newRoomType + currentHTML; And you end up with a ridiculously long answer that goes Single Double Single Triple Single Double etc. The correct way to do it would be to first get the line break by calling .innerHTML on line 05. This will retrieve and return the value of the HTML AT THAT MOMENT. Then instead of calling line.innerHTML on line 09, you would simply call line. Here is a CodePen example to illustrate the two: https://codepen.io/becky-intelletive/pen/RwGvJEm

he said in new line so it is answer B

ignore my last comment. Answer B is correct.

@02rids Thats true but we are adding </br> tag using line.innerHTML in every line. IMO answer A is correct

i think option B is correct. Because we have to show each room type in different line.

Please recheck the answer, should it be option A
