arrays - selenium ide 循环遍历数组变量

Question

在 selenium ide 中，我构建了一个测试用例，其中一个数组变量存储值。我使用 while 循环来打印这些数组变量。

在这里，我使用“getEval | myarray[0]”来打印第一个值，即“postgresql”。但未列出该值。没有错误发生。

[info] Executing: |getEval | myarray = new Array('postgresql','mysql'); | |
[info] script is: myarray = new Array('postgresql','mysql');
[info] Executing: |getEval | index=0; | |
[info] script is: index=0;
[info] Executing: |while | index < myarray.length; | |
[info] Executing: |getEval | myarray[0] | mynewvalue |
[info] script is: myarray[0]
[info] Executing: |echo | ${mynewvalue} | |
[info] echo: ${mynewvalue}
[info] Executing: |getEval | index++; | |
[info] script is: index++;
[info] Executing: |endWhile | | |
[info] Executing: |while | index < myarray.length; | |
[info] Executing: |getEval | myarray[0] | mynewvalue |
[info] script is: myarray[0]
[info] Executing: |echo | ${mynewvalue} | |
[info] echo: ${mynewvalue}
[info] Executing: |getEval | index++; | |
[info] script is: index++;
[info] Executing: |endWhile | | |
[info] Executing: |while | index < myarray.length; | | 

现在再次在同一个测试用例中，我将“getEval | myarray[0]”更改为“getEval | myarray[${index}]”以按循环索引列出数组值。

现在我收到以下错误：

[info] Executing: |getEval | myarray = new Array('postgresql','mysql'); | |
[info] script is: myarray = new Array('postgresql','mysql');
[info] Executing: |getEval | index=0; | |
[info] script is: index=0;
[info] Executing: |while | index < myarray.length; | |
[info] Executing: |getEval | myarray[${index}] | mynewvalue |
[info] script is: myarray[${index}]
[error] Threw an exception: missing ] in index expression 

我只需要 echo 打印“postgresql”，“mysql”是单独的新行。我对硒很陌生，请帮我解决这个问题。

这对我有用，希望它对其他人也有帮助......

[info] Executing: |storeEval | new Array("postgresql","mysql"); | myarray
[info] script is: new Array("postgresql","mysql");
[info] Executing: |getEval | index=0;
[info] script is: index=0;
[info] Executing: |while | index < storedVars['myarray'].length;
[info] Executing: |storeEval | index | temp
[info] script is: index
[info] Executing: |echo | javascript{storedVars['myarray'][storedVars['temp']]}
[info] echo: postgresql
[info] Executing: |getEval | index++; 
[info] script is: index++;
[info] Executing: |endWhile | | |
[info] Executing: |while | index < storedVars['myarray'].length; | 
[info] Executing: |storeEval | index | temp |
[info] script is: index
[info] Executing: |echo | javascript{storedVars['myarray'][storedVars['temp']]}
[info] echo: mysql
[info] Executing: |getEval | index++; | |
[info] script is: index++;
[info] Executing: |endWhile | | |
[info] Executing: |while | index < storedVars['myarray'].length;

这是用于剪切和粘贴的源 HTML 中的上述内容：

<tr>
<td>storeEval</td>
<td>new Array(&quot;postgresql&quot;,&quot;mysql&quot;);</td>
<td>myarray</td>
</tr>
<tr>
<td>getEval</td>
<td>index=0;</td>
<td></td>
</tr>
<tr>
<td>while</td>
<td>index &lt; storedVars['myarray'].length</td>
<td></td>
</tr>
<tr>
<td>storeEval</td>
<td>index</td>
<td>temp</td>
</tr>
<tr>
<td>echo</td>
<td>javascript{storedVars['myarray'][storedVars['temp']]}</td>
<td></td>
</tr>
<tr>
<td>getEval</td>
<td>index++;</td>
