Menu
I'm trying to make a game in javascript. I still have many issues in the code. The code is supposed to have 2 buttons; one for shuffling images dice and a button to check if the kid wrote the correct answer or not.
Here is my code.
I don't know why when I put the source of document.getElementbyID("test") it shows nothing because I want every time I click on start a random image is selected.
I would appreciate any help as I am still a beginner in javascript.
<head>
<script type="text/javascript">
function startf(){
var images = [];
index = 0;
images[0] = "<img src='1.png' length=70px width=75px>";
images[1] = "<img src='2.png' length=70px width=75px>";
images[2] = "<img src='3.png' length=70px width=75px>";
images[3] = "<img src='4.png' length=70px width=75px>";
index = Math.floor(Math.random() * images.length);
take(index);
function take(ind)
{
return document.getElementbyId("ind")="What should i put here";
}
}
function check(){
var ch=getElementbyId("answer").value;
if (ch=index+1)
{
document.getElementbyId.innerHTML="TRUE";
}
else
{
document.getElementbyId.innerHTML="False";
}
}
</script><br>
</head>
<img id="test" src="" alt="..." length="75px" width="75px" />
<body>
<input type="button" value="start" onclick="startf()">
<input id="answer" type="text" name="checkvalue" value="Enter Value" onclick="check()">
<div id="fa">
</div>
<input type="button" value=chek onclick="check()">
</body>

1- Put and end to each instructions --> ;
2- Do not use document.getElementById directly, there will be at least one occurence with an error into it and you don't want that.
function _e(id) {
return document.getElementById(id);
}
3- Always put brackets and (...) around your IF-ELSE blocks:
if (...) {
//....
} else {
//....
}
4- Every tag attributes should have " " around their values, for example:
<input type="button" value="start" onclick="check()" />
5- You could only put image paths in your array since it seems to be what needs to be updated in #test image.
