localstorage data is getting delay from services

Wed Apr 16, 2014 4:04 am

service1--------localstorgae (total_item)
service2--------localstorgae (total_point)

those services i execute on page show

now i have js script on page show to get data from those localstorgae
soemtime data is showing null
if i put an alert at my starting script being delay and data is getting properly
how may i fix this

Why localstorage data is previous data/null

available_points = localStorage.getItem("local_available_points");
total_items = localStorage.getItem("local_total_items");

for (i = 0; i < total_items; i++) {

Code: Select all

 required_points = parseInt($('#Reward_reward_grid_' + i).find("#Reward_required_points").val()); 
 btn_reward = $('#Reward_reward_grid_' + i).find("#Reward_btn_reward"); 

// alert(available_points+" "+total_items+" "+required_points); 
 if (available_points = required_points) { 
     btn_reward.css('background-color', '#BFD770'); 
     btn_reward.attr("style", "width:150px;height:50px;background-color:#BFD770;border-radius:25px !important"); 
 } else { 
     reward_more = parseInt(required_points) - parseInt(available_points); 
     reward_more = reward_more + " more check-in"; 
     btn_reward.text(reward_more); 
     btn_reward.css('background-color', '#B5B4B5'); 
     btn_reward.attr("style", "width:150px;height:50px;background-color:#B5B4B5;border-radius:25px  !important"); 
     btn_reward.attr("disabled", "disabled"); 
 }

}

Hi Deveu,

You problem is in async services.

When you invoke the service, it takes some time.

Thus if you need data from these two services please follow these steps:

1 Create new JS and fill it with code below:
pre

function ProcessYourData(){

available_points = localStorage.getItem("local_available_points");
total_items = localStorage.getItem("local_total_items");

for (i = 0; i < total_items; i++) {

required_points = parseInt($('#Reward_reward_grid' + i).find("#Reward_required_points").val());
btn_reward = $('#Reward_reward_grid' + i).find("#Reward_btn_reward");

// alert(available_points+" "+total_items+" "+required_points);
if (available_points = required_points) {
btn_reward.css('background-color', '#BFD770');
btn_reward.attr("style", "width:150px;height:50px;background-color:#BFD770;border-radius:25px !important");
} else {
reward_more = parseInt(required_points) - parseInt(available_points);
reward_more = reward_more + " more check-in";
btn_reward.text(reward_more);
btn_reward.css('background-color', '#B5B4B5');
btn_reward.attr("style", "width:150px;height:50px;background-color:#B5B4B5;border-radius:25px !important");
btn_reward.attr("disabled", "disabled");
}
}

}/pre

2 Add to the service1 "success" JS event handler. And fill it with code:
pre

if(localStorage.getItem("local_available_points"));
ProcessYourData();/pre

3 Add to the service2 "success" JS event handler. And fill it with code:

pre
if(localStorage.getItem("local_total_items"));
ProcessYourData();/pre

4 Delete your code on "page show" js event handler.

if(localStorage.getItem("local_available_points"));
ProcessYourData();

why semiclone

i think that will be

if(localStorage.getItem("local_available_points"))
{
ProcessYourData();
}

right?

I am getting 2 time data by aleart
1 is with previous data and another is new data

I added those function in success

I did this on 2 events on success

if(localStorage.getItem("local_available_points")&&localStorage.getItem("local_total_items"))
{
ProcessYourData();
}

common function in main js

getting success with previous data and why

i fix this by resting localstorage to 0 and checking on in function
