Hi guys,

I am filling a comboxbox via a CSV file.

I have 2 comboxboxes.
Comboxbox 1 is my provinces (9 of them).
comboxbox 2 gets filled pending what is selected in comboxbox 1.

This all is working GREAT. Except, i need to clear the display text of comboxbox 2.
In other words, if comboxbox 2 displayed “JOHANNESBURG”, and i re selected a new Province (comboxbox 1);
my app does re fill comboxbox 2 with the new cities, but it is still displaying the last selected city “JOHANNESBURG”.
I would like it to be BLANK.

I have tried millions of options via google, NONE working, please help,
Allternative option, if comboxbox 2 can display the first item in the newly filled items.

function processData(allText) {

var allTextLines = allText.split(/\r\n|\n/);
var headers = allTextLines[0].split(‘,’);
var lines = [];

var value = $(‘select[name=”combobox2″]’);

value.empty();

//Trying these variations to remove the displayed text in the combobox
value.val(”);
value.html(“”);

for (var i=0; i<allTextLines.length; i++) {

var x=1;
var data = allTextLines[i].split(‘,’);

if (data[0] == ProvSelected){
value.append(new Option(data [1],data [1]));
}

}

//Trying these variations to remove the displayed text in the combobox
value.val(0).change();
value.clear;

// die opsie dit die check daar, maar display nie as text nie // value[0].selectedIndex = 0;

phoneui.alert(‘done’);

}

You need to add this line to clear in MobiOne.

$(‘#m1-screenname-combobox’).val (”);

Change to your app screen name and box name.

Cheers…

Thanks for the reply.
Much appreciated, however it is not working.
The “CITY” does not blank out when i select a new “PROVINCE”.

Any other ideas?

Very weird that something so simple is being such a pain in the … 🙂

Can i mail u my app and have a loo at my sample?

regards

Have you tried forcing a screen refresh, something like this. I may have the syntax a little screwed, but I’m new to JavaScript and am posting from memory …

$(‘select[name=”combo”] option:first’).attr(”selected’,’selected’);
phoneui.preprocessorDOM(‘#m1-page’);

Hope this helps.

This will blank out the combobox2 text, make sure you update it with your screen name on the preprocessDOM

$(‘select[name=”combobox2″] :selected’).text(”)
phoneui.preprocessDOM(‘#m1-screenname’); //force UI to update

Thanks guys,

Got it to work with your help.

Almost got disponded.

The only thing that got me stuck was the phoneui.preprocessDOM.
I kept trying the PAGE and MULTIPAGE…
But the last reply made me replace it with the project name, and whooooopi.
Now i can continue to my next page…lol.

Once again, thanks you

function processData(allText) {

//phoneui.alert(‘done’);

var allTextLines = allText.split(/\r\n|\n/);
var headers = allTextLines[0].split(‘,’);
var lines = [];

var value = $(‘select[name=”combobox1″]’);

value.empty();
$(‘select[name=”combobox1″] :selected’).text(”)

for (var i=0; i<allTextLines.length; i++) {

var x=1;
var data = allTextLines[i].split(‘,’);

if (data[0] == ProvSelected){
value.append(new Option(data [1],data [1]));
}

}

$(‘select[name=”combobox1″] option:first’).attr(‘selected’,’selected’);
phoneui.preprocessDOM(“#m1-golfcoursefinder”);

}

careldegoede,

is it possible to post your project?
Trying to fill comboboxes through .csv and give conditions to the comboboxes but can’t get it to work.

Thanks
