My problem is that I don't know how to show the innerhtml of my form.
The form is like a survey form and once you clicked the submit button, all the contents I had answered would show like a summary page...
function displayResult() { var first = document.getElementById("first").value; var middle = document.getElementById("middle").value; var last = document.getElementById("last").value; alert("oh"); var maincontent = document.getElementById("content").innerHTML; maincontent = "
" + first; }
回答1:
var maincontent = document.getElementById("content").innerHTML; maincontent = "
" + first;
On the second line you're overwriting the variable, not setting the .innerHTML. This is what you want:
var maincontent = document.getElementById("content"); maincontent.innerHTML = "
" + first;
Also, you must make sure the elements with ids of "first" "middle" and "last" actually exist, or this might cause a TypeError.

But , you should have id as first. and you should need content div in html part.
回答3:
Instead of this:
var maincontent = document.getElementById("content").innerHTML; maincontent = "
" + first;`
Try this:
document.getElementById("content").innerHTML = "
" + first;
You may also want to use .innerHTML to get 'first', rather than .value? I'm not sure what kind of element 'first' is.

What is your element with id "contend" , a div? td? tr? or ? The way it should be is
