hi all,

I am using following code on tap of a button in my app to add some item to my cart on the server.

Ext.data.JsonP.request({
url : localStorage.getItem('serverPath') + 'addToCart.php',
//callbackKey: 'callback',
params: {
strEmail: sessionStorage.getItem('loginUserId'),
customerId: sessionStorage.getItem('customerId'),
productSKU: sizeRecord[0].get('sizeSkuModifier') + productInfoStore.get('sku') + finishRecord.get('text'),//"MC-3X51073460",=> sizeSkuModifiers + SKU + ColorSKUModifiers
productPrice: finishRecord.get('price'),
productID: productInfoStore.get('productId'),
variantID: finishRecord.get('variantId'),
quantity: '1',
chosenColor: color,
chosenColorSKUModifier: colorSKU,
chosenSize: sizeRecord[0].get('size'),
chosenSizeSKUModifier: sizeRecord[0].get('sizeSkuModifier')
},
success: function(response,opts) {

sessionStorage.setItem('customerId', response.addItemsToCartResult);//store customerId for future use
localStorage.setItem('customerId', response.addItemsToCartResult);

if(cartStoreOffline.getCount() != 0) {
if(!me.offlineCartItemsPanel){
me.offlineCartItemsPanel = Ext.create('Wilsonart.view.tablet.OfflineCartItems');
}
me.offlineCartItemsPanel.show();
}
else {
me.onSuccessAddToCart();
}

Ext.getCmp('addToCart').enable();
},
failure: function(response,opts) {
if (response.timedout) {
Ext.Msg.alert(captions.get('timeout'), captions.get('serverTimeout'));
}
else if (response.aborted) {
Ext.Msg.alert(captions.get('aborted'), captions.get('requestAborted'));
} else {
Ext.Msg.alert(captions.get('bad'), captions.get('invalidRequest'));
}
Ext.getCmp('addToCart').enable();
}
});

It works fine except that it makes multiple entries on the server even I have tapped the button only once. To overcome the situation I disabled the button once it is tapped and I am enabling it only after receiving response from server. but it also doesn't works.

Please help me.
