This code, which I've found somewhere online, works fine and it's kind of what I'm trying to accomplish:
$(document).ready(function(){
var arrData = [ "j", "Q", "u", "e","r","y" ];
alert(jQuery.inArray("Q", arrData));
});
However, I have an array from a loop with php/mysql that I output and save like this:
$query = mysql_query("SELECT * FROM geo_orter");
while(($row = mysql_fetch_assoc($query))){
$i = $row['ort_id'];
$result[$i] = $row['ortnamn'];
};
$allaOrterjson=json_encode($result);
Then I go ahead and do this, which works:
var allaOrter=<?php echo $allaOrterjson ?>;
document.write(allaOrter[0] + allaOrter[1] + allaOrter[2]);
and gives me
undefinedAborremålaAbbjörnahall
Here's the issue:
I tried
$(document).ready(function(){
alert(jQuery.inArray("Aborremåla", allaOrter));
});
but it results in "-1" (Not found).
I'm trying to find out the index nr of an item in the array. Any ideas?
Log result:
The problem here is that json_encode($result);
creates a JSON object, not an array. Hence jQuery.inArray
isn't working.
Build a JavaScript array instead: [ "value", "value", "value", etc... ];
Or do something like this with the object:
var locations = {
"Abårremöla" : 1,
"Stuff" : 2,
"Ludvika" : 1549
};
var query = "Ludvika";
if(query in locations) {
var id = locations[query];
alert(id); //displays 1549
}
For that to work you have to build up the object the other way around in PHP - so a PHP array with the location name as the indexer and the id as the value:
$query = mysql_query("SELECT ort_id, ortnamn FROM geo_orter");
while(($row = mysql_fetch_assoc($query))){
$index = $row['ortnamn']; //<- note!
$result[$i] = $row['ort_id']; //<- note!
};
$allaOrterjson=json_encode($result);
Try this
var my_cars= new Array()
my_cars[0]="Mustang";
my_cars["family"]="Station Wagon";
my_cars["big"]="SUV";
for( var i in my_cars ){
console.log( my_cars[i] );
}
var n = {
"0": "Mustang",
"family": " Station Wagon",
"big": "SUV"
};
for( var i in n ){
console.log( n[i] );
}
