Concatenating 2 variables as one

**fowler1979** · 08-16-2012 10:30 AM

Hello guys, sometimes I get stuck in simple matters while coding... this is one of them. OK, very simple:

Code:

function test(objID1, objID2, objID3, objID4) {
for (i=1; i<5; i++) {
alert('The object:' + objID[i] + 'is stupid');
}

Is this possible? Joining in two variables as one?

Thanks.

Does not make sense...

1. Are objID1 ... ObjID4 arrays? Or are they simple strings?

Need more information.

Hi JMRKER
simple strings.

This is just a question if it is possible to join a variable names with other.

Still not sure what you are trying to accomplish...

Code:

<!DOC HTML>
<html>
<head>
<title> Untitled </title>
<script type="text/javascript">
// do you mean this
var var1 = 'abc';
var var2 = 'def';
alert('var1+var2 = '+var1+var2);

// or do you mean
var var12 = var1 + var2;
alert('var12 = '+var12);

// or are you trying to do something like this...
window[var1+var2] = var1+var2;
alert('abcdef = '+window[var1+var2]);

// finally, this...
window['var12'] = var1+var2;
alert(window['var12']);

// or something else???

</script>


</head>

In this particular test of yours I would recommend accessing the variables via the arguments object instead:

Code:

function test()
{
	var i;
	for (i = 0; i < arguments.length; ++i) {
		alert('The object: ' + arguments[i] + ' is stupid');
	}
}

test('one', 'two', 'three');

Let's put it like this:

Code:

function funcTest(objID1, objID2, objID3, objID4, objID5, objID6, objID7, objID8, objID9, objID10) {

	var arrObjects=[];
	for (i=0; i<10; i++) {
		arrObjects[i]=objID[i];
		}

}

}

Have you tried using post #5?

If yes, what was the problem orwhat error are you getting?

How does your code differ from this test?

Code:

<!DOC HTML>
<html>
<head>
<title> Untitled </title>
<script type="text/javascript">

function $_(IDS) { return document.getElementById(IDS); }

function funcTest() {
  var arrObjects=[];
  for (var i = 0; i < arguments.length; ++i) { arrObjects[i]=arguments[i]; }

  alert(arrObjects.join('\n'));
}
</script>

</head>
<body>
<input type="text" id="TBox" value="Text Box">
<p>
<input type="radio" name="RBtn" id="RBtn0" value="0">RBtn 1
<input type="radio" name="RBtn" id="RBtn1" value="1">RBtn 2
<input type="radio" name="RBtn" id="RBtn2" value="2">RBtn 3
<input type="radio" name="RBtn" id="RBtn3" value="0">RBtn 1
<input type="radio" name="RBtn" id="RBtn4" value="1">RBtn 2
<input type="radio" name="RBtn" id="RBtn5" value="2">RBtn 3
<p>
<input type="checkbox" id="CBox0" name="CBox0" value="A">CBox A
<input type="checkbox" id="CBox1" name="CBox1" value="B">CBox B
<p>
<select id="SBox" name="SBox" id="SBox">
 <option value="">Pick</option>
 <option value="1">1</option>
 <option value="2">2</option>
 <option value="3">3</option>
 <option value="4">4</option>
 <option value="5">5</option>
 <option value="6">6</option>
</select>
<p>
<button
 onclick="funcTest($_('TBox').id, $_('RBtn0').id, $_('RBtn1').id, $_('RBtn2').id, $_('RBtn3').id, $_('RBtn4').id, $_('RBtn5').id,  $_('CBox0').id, $_('CBox1').id,  $_('SBox').id)">Show IDs</button>
</body>
</html>

Nevermind guys, I've completely redesigned my code with arrays.
Thanks anyway.
