Question

i have many pieces of code like:

<script type="text/javascript">
dojo.query("body").delegate("#input0 > select.estatistica", "onchange", function(evt){
        dojo.xhrPost({
            url: "drop2.php",
            handleAs: "json",
            postData: "data=" + $(this).val(),
            preventCache: true,
            load: function(json) {
                $m0 = [];

                for (var i = 1; i < 10; i++) {
                    $m0.push(parseFloat(json[i]["valor" + i]));
                }
                dojo.addOnLoad(refreshChar0);

            }
        });
    });
</script>


<script type="text/javascript">
dojo.query("body").delegate("#input1 > select.estatistica", "onchange", function(evt){
        dojo.xhrPost({
            url: "drop2.php",
            handleAs: "json",
            postData: "data=" + $(this).val(),
            preventCache: true,
            load: function(json) {
                $m1 = [];

                for (var i = 1; i < 10; i++) {
                    $m1.push(parseFloat(json[i]["valor" + i]));
                }
                dojo.addOnLoad(refreshChart1);
            }
        });
    });
</script>

i tried this loop, but i am not sure about the script. Probably i have syntax errors.

<script type="text/javascript">
for(x=0; x<10; x++) {
dojo.query("body").delegate("'#input'+x+'> select.estatistica'", "onchange", function(evt) {
        dojo.xhrPost({
            url: "drop2.php",
            handleAs: "json",
            postData: "data=" + $(this).val(),
            preventCache: true,
            load: function(json) {
                $m+x = [];

                for (var i = 1; i < 10; i++) {
                    $m+x.push(parseFloat(json[i]["valor" + i]));
                }
                dojo.addOnLoad(refreshChart+x);
            }
        });
    });
}
</script>

thanks

Answer 1

to create a variable name dynamicaly you have to use bracket notation

e.g: this['$m'+x] or window['$m'+x] will create a variable called $m1 where x = 1

try:

window['foo' + 'bar'] = 'hello';
alert(foobar);
