I have an array in localstorage and would like to add a delete button to allow enduser to delete an item from this list

Hello!
You can delete an item with this function

code
function removeArrayItem(varName, itemValue) {
var arr = myLoad(varName);
if(arr.indexOf(itemvalue) != -1) {
arr.splice(arr.indexOf(itemvalue));
localStorage.setItem(varName, JSON.stringify(arr));
}
} /code

To get selected item from selectmenu1 use following code:
code Tiggr('selectmenu1').val()/code

thanks Katya,
I didn't get it to work, heres what I did

1 create new java, pasted script

function removeArrayItem(varName, itemValue) {
var arr = myLoad(varName);
if(arr.indexOf(itemvalue) != -1) {
arr.splice(arr.indexOf(itemvalue));
localStorage.setItem(varName, JSON.stringify(arr));
}
}

1. on click event add, run custom javascript
   Tiggr('mobileselectmenu1').val()

   can you tell me what it may be

   cheers

Try adding following JS code on click event:
code
removeArrayItem('variable_name', Tiggr('mobileselectmenu2').val());
setSelectMenuOptions(Tiggr('mobileselectmenu2'), myload('variable_name'));
/code

No luck Katya,
added script, no change, I can share if you wish

Yes, please share your project with support@tiggzi.com. We will test and I'll update.

thank you Katya,
now shared

There is a mistake. Please correct your JS in click event. There must be "mobileselectmenu1" instead of "mobileselectmenu2".

Thank you Kayta,
I should have seen that, sorry.

Works great on browser but when loaded on android galaxy ace, white screen only, app installs but only white screen shows, any Ideas why?

We are testing. I will update.
