This is a basic quiz. Only about 3 questions. I'm having issue with the
answer key which stays on a certain value regardless of acknowledging that
you have the correct answer for the first and moving on to the next answer.
Here's the code:
Expand|Select|Wrap|Line Numbers
- <html><head><title>Problem7</title>
- <script type="text/javascript">
- function attachHandlers()
- {
- var my_button = document.getElementById("sec_button");
- my_button.onclick = checkAnswer;
- }
- function firstQuestion()
- {
- var the_box = document.getElementById("questions");
- var first_ques = "what's the value of 5+4?";
- the_stat = document.createTextNode(first_ques);
- the_box.appendChild(the_stat);
- }
- function checkAnswer()
- {
- var the_questions = new Array();
- the_questions[1] = "what's the value of 7+4?";
- the_questions[2] = "what's the value of 9+6?";
- the_questions[3] = "what's the value of 10+6?";
- var the_key = new Array();
- the_key[0] = "9";
- the_key[1] = "11";
- the_key[2] = "15";
- the_key[3] = "16";
- var the_field = document.getElementsByTagName("input")[0];
- var i=0;
- while(i < the_key.length)
- {
- if (the_field.value==the_key[i])
- {
- alert("Very Good");
- i++;
- }
- else
- {
- alert("Please try again");
- return
- }
- the_field.value="";
- var the_div = document.getElementById("questions");
- the_div.innerHTML="";
- var text_node = document.createTextNode(the_questions[i]);
- the_div.appendChild(text_node);
- }
- }
- </script></head>
- <body onLoad="attachHandlers(); firstQuestion();">
- <div id = "questions"></div>
- <input type="text" id="answerfield" size="20"><br>
- <input type="button" value="check" id="sec_button">
- </body>
- </html>
the button....
I know it's probably a simple step missing, but I can't seem to find it.
