[jira] [Commented] (CB-6763) Simultaneous local XHRs on WP8 returns
incorrect result
[ https://issues.apache.org/jira/browse/CB-6763?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14010287#comment-14010287 ]
Jesse MacFadyen commented on CB-6763:
-------------------------------------
The example above is a classic closure issue, and not related to the XHRHelper class, or the JS code it injects.
>From : http://stackoverflow.com/questions/750486/javascript-closure-inside-loops-simple-practical-example
{code}
var funcs = [];
for (var i = 0; i < 3; i++) { // let's create 3 functions
funcs[i] = function() { // and store them in funcs
console.log("My value: " + i); // each should log its value.
};
}
for (var j = 0; j < 3; j++) {
funcs[j](); // and now let's run each one to see
}
{code}
My value: 3
My value: 3
My value: 3

> Key: CB-6763
> URL: https://issues.apache.org/jira/browse/CB-6763
> Project: Apache Cordova
> Issue Type: Bug
> Components: WP8
> Affects Versions: 3.4.0
> Reporter: Vladimir Kotikov
> Assignee: Jesse MacFadyen
> Labels: wp8, xhr, xhrhelper
>
> When try to get content of multiple local files via XHR, all requests return responses with same content. E.g. following code (using jQuery)
> {noformat}
> function loadTemplates (views) {
> var deferreds = [];
> $.each(views, function (index, view) {
> var vURL = 'tpl/' + view + '.html';
> deferreds.push($.get(vURL, function (data) {
> console.log(data)
> }, 'html'));
> })
> }
> loadTemplates(["HomeView", "ContactView", "ShellView", "EmployeeView", "EmployeeSummaryView", "EmployeeListItemView"]);
> {noformat}
> will print contents of {{tpl/EmployeeListItemView.html}} 6 times.
> The problem is when new local XHR is sent, it overrides {{__onXHRLocalCallback}} callback, already created by previous request.
