PhoneGap的ChildBrowser JavaScript的执行 [英] PhoneGap ChildBrowser Executing JavaScript

问题描述

我不知道这是否可以执行的PhoneGap childbrowser窗口内的JavaScript，所以我们可以在PhoneGap的应用程序操作的网站？

I wonder if this is possible to execute JavaScript inside phonegap childbrowser window so we can manipulate websites under phonegap app?

纵观大局作为一个可以创建Objective-C的一个函数，它会执行JS成childbrowser（修改childbrowser.m和childbrowser.h文件）和创建它的JS封装所以可以调用JS函数来执行JS里面childbrowser。

Looking at the big picture as one can create a function in Objective-C which executes that JS into childbrowser (modifying childbrowser.m and childbrowser.h files) and creating JS wrapper of it so one can call JS function to execute JS inside childbrowser.

我要你修改ChildBrowser对我来说有一个功能，所以我不应该失去这样做。至少给我的最初步骤。

I want you to modify ChildBrowser for me to have that functionality so I shouldn't lost doing it. At least give me initial steps.

ChildBrowser.js

ChildBrowser.js

/* MIT licensed */
// (c) 2010 Jesse MacFadyen, Nitobi

function ChildBrowser()
{

}

// Callback when the location of the page changes
// called from native
ChildBrowser._onLocationChange = function(newLoc)
{
    window.plugins.childBrowser.onLocationChange(newLoc);
}

// Callback when the user chooses the 'Done' button
// called from native
ChildBrowser._onClose = function()
{
    window.plugins.childBrowser.onClose();
}

// Callback when the user chooses the 'open in Safari' button
// called from native
ChildBrowser._onOpenExternal = function()
{
    window.plugins.childBrowser.onOpenExternal();
}

// Pages loaded into the ChildBrowser can execute callback scripts, so be careful to 
// check location, and make sure it is a location you trust.
// Warning ... don't exec arbitrary code, it's risky and could cause your app to fail.
// called from native
ChildBrowser._onJSCallback = function(js, loc)
{
    // Not Implemented
    window.plugins.childBrowser.onJSCallback(js, loc);
}

/* The interface that you will use to access functionality */

// Show a webpage, will result in a callback to onLocationChange
ChildBrowser.prototype.showWebPage = function(loc)
{
    PhoneGap.exec("ChildBrowserCommand.showWebPage",loc);
}

// close the browser, will NOT result in close callback
ChildBrowser.prototype.close = function()
{
    PhoneGap.exec("ChildBrowserCommand.close");
}

// Not Implemented
ChildBrowser.prototype.jsExec = function(jsString)
{
    // Not Implemented!!
    PhoneGap.exec("ChildBrowserCommand.jsExec", jsString);
}

// Note: this plugin does NOT install itself, call this method some time after deviceready to install it
// it will be returned, and also available globally from window.plugins.childBrowser
ChildBrowser.install = function()
{
    if(!window.plugins)
    {
        window.plugins = {};    
    }

    window.plugins.childBrowser = new ChildBrowser();
    return window.plugins.childBrowser;
}

我的全局变量。

var CB = null;

在我的DeviceReady事件。

On my DeviceReady event.

CB = ChildBrowser.install();
if (CB != null) {
    CB.onLocationChange = onCBLocationChanged;
}

我可以用执行任何JS进入网页。

I can execute any JS into webpage using.

CB.jsExec("alert('I am from ChildBrowser!');");

我希望我的这一贡献将带给你脸上的微笑。

I hope my contribution to this will bring smile on your face.
