問題描述

selenium 中的 runScript 命令真的很有用，我用它來匯總表中的值，然后像這樣存儲值

The runScript command in selenium is really useful, and I'm using it to total values in a table and then store the value like this

<tr>
    <td>runScript</td>
    <td>var cumulative = 0.0; $('table.quote-review-group-component').eq(0).find('tr').each( function( i,el ){var singleStackTotal = $(el).find('td').eq(4).html();if( singleStackTotal ){cumulative += parseFloat( singleStackTotal.substring(1) );} }); cumulative = cumulative.toFixed(2)</td>
    <td></td>
</tr>
<tr>
    <td>storeEval</td>
    <td>selenium.browserbot.getUserWindow().cumulative</td>
    <td>cumulative</td>
</tr>
<tr>
    <td>echo</td>
    <td>${cumulative}</td>

    <td></td>
</tr>
<tr>
    <td>verifyEquals</td>
    <td>￡${cumulative}</td>
    <td>${total}</td>
</tr>

理想情況下，我希望能夠指向外部 js 文件，而不是將命令中的 javascript 作為字符串，這樣我就可以加載一些測試函數并使用 storeEval 來獲取函數的返回

Ideally I'd like to be able to point to an external js file rather than have the javascript in the command as a string, so that I can load in some test functions and use storeEval to get the return of the function

所以我們有

<tr>
    <td>runExternalScript</td>
    <td>/path/to/external/extra-tests.js</td>
    <td></td>
</tr>
<tr>
    <td>storeEval</td>
    <td>selenium.browserbot.getUserWindow().getCumulative(0)</td>
    <td>cumulative0</td>
</tr>
<tr>
    <td>verifyEquals</td>
    <td>￡${cumulative}</td>
    <td>${total}</td>
</tr>

外部腳本看起來像這樣

function checkSingleGroupListTotal( index ){
    if ( index == "undefined" ){
        index = 0;
    }
    var cumulative = 0.0; 
    $('table.quote-review-group-component').eq(index).find('tr').each( function( i,el ){
        var singleStackTotal = $(el).find('td').eq(4).html();    
        if( singleStackTotal ){         
            cumulative += parseFloat( singleStackTotal.substring(1) );     
        } 
    }); 
    return cumulative.toFixed(2);
}

考慮一個插件，它添加一個 loadScript 動作來檢查外部 js 文件，然后將文件內容傳遞給 runScript 就可以完成這項工作.但我不想重新發明輪子，而且我之前從未構建過插件.

Thinking about it a plugin which adds a loadScript action which checks for the external js file and then passes the file contents to runScript would do the job. But I don't want to reinvent the wheel, and I've never built a plug in before.

推薦答案

runScript 命令只是將包含腳本的 <SCRIPT> 元素添加到 DOM 并讓瀏覽器運行它.你可以自己做同樣的事情，而不是使用內嵌腳本，使用 SRC= 屬性來告訴瀏覽器要加載什么文件.您可能必須從 Web 服務器加載文件，因為某些瀏覽器不允許從網絡加載的頁面訪問 file: URL.

The runScript command merely adds a <SCRIPT> element containing the script to the DOM and lets the browser run it. You can do the same yourself, and instead of an in-line script, use the SRC= attribute to tell the browser what file to load. You may have to load the file from a web server, because some browsers won't allow page loaded from the net to access a file: URL.
