Question

我正在尝试执行一个使用RequireJS（2.1.8），WireJS（0.10.2）和PhantomJS（1.9.2）的基本应用程序：

使用PhantomJS运行应用程序时（这是我的目标），WireJS无法加载（请参阅下面的错误）。
使用Chrome运行应用时，它会正常完成。

请帮助指出WireJS在PhantomJS下正常运行的缺失部分。

以下是我的应用文件。

1）app.html

<!DOCTYPE html>

<html lang="en">
<head>
<meta charset="utf-8">
<title>SaphirJS.core</title>
<script data-main="app" src="../../../target/deps/require-0.0.1/2.1.8/require.js">  </script>
</head>
<body>
</body>
</html>

2）app.js

"use strict";

require.config({
    baseUrl: ".",

    packages: [
        { name: 'wire', location: '../../../target/deps/wire-0.0.1/0.10.2', main: 'wire' },
        { name: 'when', location: '../../../target/deps/when-0.0.1/2.4.1', main: 'when' },
        { name: 'meld', location: '../../../target/deps/meld-0.0.1/1.3.0', main: 'meld' }
    ]
});

require(["wire!wireContext"], function(wireContext) {
    alert(wireContext.message);
});

3）wireContext.js

define({
    message: "Hello World!"
});

4）phantom-runner.js

(function() {
    'use strict';

    var args = require('system').args,
        timeoutRef = undefined,
        timeLimit = 10000;

    // arg[0]: scriptName, args[1...]: arguments
    if (args.length !== 2) {
        console.error('Usage:\n  phantomjs runner.js [url-of-your-qunit-testsuite]');
        phantom.exit(1);
    }

    var url = args[1],
        page = require('webpage').create();

    // Route `console.log()` calls from within the Page context to the main Phantom context (i.e. current `this`)
    page.onConsoleMessage = function(msg) {
        console.log(msg);
    };

    page.onInitialized = function() {
        timeoutRef = setTimeout(function(){
            console.error('Test Run Failed. Timeout Exceeded. Took longer than '+ timeLimit / 1000 +' seconds.');
            phantom.exit(1);
        }, timeLimit);
    };

    page.onAlert = function(message) {
        clearTimeout(timeoutRef);
        phantom.exit(0);
    };

    page.open(url, function(status) {
        if (status !== 'success') {
            console.error('Unable to access network: ' + status);
            phantom.exit(1);
        }
    });
})();

5）在PhantomJS下运行应用程序时的错误

Answer 1

你是对的，Younes。由于某种原因，PhantomJS不支持Function.prototype.bind。

您可以使用cujoJS/poly或kriskowal/es5-shim来填充Function.prototype.bind。

Answer 2

正如问题评论中所提到的，这个问题的根源是PhantomJS没有实现'Function.prototype.bind（）'函数。

正如PhantomJS和WireJS的人员所建议的，使用ES5 polyfill可以解决问题。 MDN建议的实施没有帮助，因为它是规范的部分实现。 CujoJS / PolyJS中包含的实现解决了我的问题。现在，WireJS对PhantomJS很满意。

以下是app.js的新版本

"use strict";

require.config({
    baseUrl: ".",

    packages: [
        { name: 'wire', location: '../../../target/deps/wire-0.0.1/0.10.2', main: 'wire' },
        { name: 'when', location: '../../../target/deps/when-0.0.1/2.4.1', main: 'when' },
        { name: 'meld', location: '../../../target/deps/meld-0.0.1/1.3.0', main: 'meld' },
        { name: 'poly', location: '../../../target/deps/poly-0.0.1/0.5.2', main: 'poly' }
    ]
});

require(["poly/function", "wire!appWireContext"], function(poly, wireContext) {
    alert(wireContext.message);
});

干杯
