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(这是我的目标)运行应用程序时,WireJS 无法加载(请参阅下面的错误)。
  • 使用 Chrome 运行应用程序时,它可以正常完成。

请帮助指出 WireJS 在 PhantomJS 下正常运行的缺失部分。

以下是我的应用程序文件。

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) 应用程序.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) 幻象运行器.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app时报错

你是对的,尤尼斯。Function.prototype.bindPhantomJS出于某种原因 不支持。

您可以Function.prototype.bind使用cujoJS/polykriskowal/es5-shim 进行 polyfill

正如对问题的评论中提到的,这个问题的根源是 PhantomJS 没有实现 'Function.prototype.bind()' 函数。

正如 PhantomJS 和 WireJS 的人所建议的,这个问题将使用 ES5 polyfill 解决。MDN 建议的实现没有帮助,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。

以下是新版本的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' },
        { 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
