如何传递参数到PhoneGap上构建的应用程序 [英] How to pass arguments to app built on Phonegap

问题描述

我正在使用JQM和Phonegap编写一个应用程序来部署在iOS上，我需要它来读取输入参数，像一个常见网站的URL参数在javascript中通过处理对象'window.location.search'

在我的情况下，应用程序将从网站启动，如下所示：

 < a href =myapp：//？arg1 = 1& arg2 = 2>我的应用程式< / a> 
  

现在工作正常了，我已经可以打电话给我的应用程序了，参数arg1，arg2等等我试过阅读window.location.search但没有运气。

我该如何做？我需要写一些Objective C代码吗？

任何建议都会感激。

解决方案

我的问题已解决使用此链接的内容： https://gist.github.com/859540

代码为：

Objective-c part：

在MainViewController.m中：

  - （BOOL）应用程序：（UIApplication *）应用程序didFinishLaunchingWithOptions：（NSDictionary *）launchOptions 
 {
 //执行任何自定义启动的东西你需要... 
 //处理你的启动选项
 NSArray * keyArray = [launchOptions allKeys]; 
 if（[launchOptions objectForKey：[keyArray objectAtIndex：0]]！= nil）
 {
 //我们存储字符串，所以我们可以使用它后，webView加载
 NSURL * url = [launchOptions objectForKey：[keyArray objectAtIndex：0]]; 
 self.invokeString = [url absoluteString]; 
 NSLog（@amp;launchOptions =％@，url）; //如果你想看看发生了什么
} 
 //调用super，因为它是非常重要的（99％的phonegap功能从这里开始）
 return [super application：application didFinishLaunchingWithOptions： launchOptions]; 
} 
 
 
  - （void）webViewDidFinishLoad：（UIWebView *）theWebView 
 {
 //仅当___ PROJECTNAME __- Info.plist指定协议处理
 if（self.invokeString）
 {
 //这是在deviceready事件被触发之前传递的，所以你可以在js中访问它，当你收到deviceready 
 NSString * jsString = [NSString stringWithFormat：@var invokeString = \％@ \;，self.invokeString]; 
 [theWebView stringByEvaluatingJavaScriptFromString：jsString]; 
} 
 
 //背景的黑色基色匹配原生应用程序
 theWebView.backgroundColor = [UIColor blackColor]; 
 
 return [super webViewDidFinishLoad：theWebView]; 
} 
  

在使用cordova-1.7.0的index.html文件中：

  function onDeviceReady（）
 {
 alert（invokeString）; 
} 
  

警报已返回：myapp：//？arg1 = 1& arg2 = / p>

只是使用相同的字串来呼叫...：）

I'm writing an app using JQM and Phonegap to deploy on iOS and I need it to read input arguments like a url arguments of a common website does in javascript by handling the object 'window.location.search'

In my situation, the app will be launched from a website, like this:

<a href="myapp://?arg1=1&arg2=2"> My App </a>

This is working right now, I can already call my app, what I need now is to read the arguments arg1, arg2, etc. I've tried reading window.location.search but with no luck.

How can I do this? Do I need to write some Objective C code?

Any suggestions would be appreciated.

Thanks.

解决方案

My problem was solved using the content of this link: https://gist.github.com/859540

The code is:

Objective-c part:

In MainViewController.m:

    - (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
    // perform any custom startup stuff you need to ...
        // process your launch options
    NSArray *keyArray = [launchOptions allKeys];
    if ([launchOptions objectForKey:[keyArray objectAtIndex:0]]!=nil) 
    {
               // we store the string, so we can use it later, after the webView loads
        NSURL *url = [launchOptions objectForKey:[keyArray objectAtIndex:0]];
        self.invokeString = [url absoluteString];
        NSLog(@amp;" launchOptions = %@",url); // if you want to see what is happening
    }
    // call super, because it is super important ( 99% of phonegap functionality starts here )
    return [super application:application didFinishLaunchingWithOptions:launchOptions];
}


- (void) webViewDidFinishLoad:(UIWebView*) theWebView 
{
     // only valid if ___PROJECTNAME__-Info.plist specifies a protocol to handle
     if (self.invokeString)
     {
        // this is passed before the deviceready event is fired, so you can access it in js when you receive deviceready
        NSString* jsString = [NSString stringWithFormat:@"var invokeString = \"%@\";", self.invokeString];
        [theWebView stringByEvaluatingJavaScriptFromString:jsString];
     }

     // Black base color for background matches the native apps
     theWebView.backgroundColor = [UIColor blackColor];

    return [super webViewDidFinishLoad:theWebView];
}

In the index.html file using cordova-1.7.0:

function onDeviceReady()
    {
        alert(invokeString);
    }

alert returned: myapp://?arg1=1&arg2=2

just the same string used to call it ... :)
