if statment to output image

**Farmlord** · 05-25-2012 12:54 PM

Hi guys i goy a problem with my js. I have got 4 if statements on a page were if the user enters for example 25 the box will turn blue. Now what I want is that after the user inputs 4 things and all boxes are blue I want an image to appear. I will post the code and the codes which I have tried.

Code:

function changecolour1(textbox) { 	//Function name and passing it the priamter textbox
var val = textbox.value; 		//Everthing on the right side gets copyed to the left side
if (val == 26) { 			//checks if val has the value of 26
	textbox.style.backgroundColor = 'blue'; 	//if it dose it will go blue
	}
	else {
	textbox.style.backgroundColor = 'red'; 		//if it dose not match it will go red 
	}
addresult()
}

function changecolour2(textbox) {
var val = textbox.value;
if (val == 20) {
	textbox.style.backgroundColor = '0000FF';
	}
	else {
	textbox.style.backgroundColor = 'FF0000';
	}
}

function changecolour3(textbox) {
var val = textbox.value;
if (val == 63) {
	textbox.style.backgroundColor = 'blue';
	}
	else {
	textbox.style.backgroundColor = 'red';
	}
}

function changecolour4(textbox) {
var val = textbox.value;
if (val == 36) {
	textbox.style.backgroundColor = 'blue';
	}
	else {
	textbox.style.backgroundColor = 'red';
	}
}

Code:

function addresult() {
var val = Inputbox1.value;
	if ( val == 1) {
		alert ("Foo")
	}
}

Any help would be great.

can you post your html and show how you call all these functions?

Hi ye sure. However the boxes work fine its the image that i wawnt to pop up that dose not work.

Code:

<div class = "Questionbox1">
	<form name="form1" id="form1" action="#">
	<input type="text" id="mytext" name="mytext" value="" onkeyup="changecolour1(this)" >
	</form>
	</div>

That was just an example of how i call one of them

here's one way to simplify things - you can change the div that gets displayed to an image or whatever...

Code:

<html>
<head>
<style>
#hi{display:none}
</style>
</head>
<body>
<div id="questions">
<input type="text" id="text26" name="mytext1" />
<input type="text" id="text23" name="mytext2" />
<input type="text" id="text63" name="mytext3" />
<input type="text" id="text36" name="mytext4" />
</div>
<div id="hi">Hello there!</div>
<script type='text/javascript'>
var inps=document.getElementById("questions").getElementsByTagName("input")
var show=false;
for (var i = 0; i < inps.length; i++) {
inps[i].onkeyup=function(i){
return function(){
inps[i].style.backgroundColor=inps[i].value==inps[i].id.replace("text","")?"blue":"red"
for (var a = 0; a < inps.length; a++) {	
	show=inps[a].style.backgroundColor=="blue"?true:false;
	}
document.getElementById("hi").style.display=show?"block":"none"	
			}
	}(i)
}

</script>
</body>
</html>

Thank you very much for the help

**xelawho** · 05-25-2012 06:01 PM

you're welcome. here's a slightly simpler version that hides it again if the user changes one of the text box values:

Code:

<script type='text/javascript'>
var inps=document.getElementById("questions").getElementsByTagName("input")

for (var i = 0; i < inps.length; i++) {
inps[i].onkeyup=function(){
var show=false;
this.style.backgroundColor=this.value==this.id.replace("text","")?"blue":"red"
for (var a = 0; a < inps.length; a++) {	
	show=inps[a].style.backgroundColor=="blue"?true:false;
	}
document.getElementById("hi").style.display=show?"block":"none"	
	}
}

</script>

Ah thank you again very much

**xelawho** · 05-25-2012 11:39 PM

one last tweak

Code:

<script type='text/javascript'>
var inps=document.getElementById("questions").getElementsByTagName("input")

for (var i = 0; i < inps.length; i++) {
inps[i].onkeyup=function(){
var show=true;
this.style.backgroundColor=this.value==this.id.replace("text","")?"blue":"red"
for (var a = 0; a < inps.length; a++) {	
	if(inps[a].style.backgroundColor!="blue"){
	show=false;
	break;
		}
	}
document.getElementById("hi").style.display=show?"block":"none"	
	}
}

</script>
