如何单击带有没有id标记的caspejs的复选框

Question

我有以下HTML代码：

<tr class="job_summary_a">
      <td><input type="CHECKBOX" name="job_id" value="20180601054414"></td>
      <td>&nbsp;</td>
      <td><a href="/test/?sec=job&amp;subsec=view_job&amp;job_id=20180601054414&amp;job_folder=TT">20180601054414</a></td>
      <td>&nbsp;</td>
      <td>Test case 01</td>
      <td>&nbsp;</td>
      <td>Network test</td>
      <td>&nbsp;</td>
      <td>06/01/2018 05:44:14</td>
      <td>&nbsp;</td>
      <td>Completed</td>
    </tr>

我在点击带有casperjs的复选框时遇到问题！ 我现在的casperjs代码是：

var jobCheck = casper.evaluate(function () {
    return [].map.call(__utils__.findAll('table tr td:nth-child(1)'), function (e) { return e.innerHTML; });
});
var jobID = casper.evaluate(function () {
    return [].map.call(__utils__.findAll('table tr td:nth-child(3)'), function (e) { return e.innerHTML; });
});
var jobsTitle = casper.evaluate(function () {
    return [].map.call(__utils__.findAll('table tr td:nth-child(5)'), function (e) { return e.innerHTML; });
});
var link = ""
var count = 0
for (var i = 1; i < rows; i++) {
     console.log('Checking...row: ' + i + '...' + jobsTitle[i] + '...found');
     link = JSON.stringify(jobID[i + 1]);
     job = link.match(/job_id=(\d+\S\d+)/)[1];
     console.log('Job ID: ' + job);
     if (job === default_id) {
         console.log('skipping!');
     }
     else {
         console.log('marked to remove...jobId:' + job);
         var sel = 'input[value="' + job + '"]';
         var name = this.evaluate(function(job) {
              document.querySelector(sel).click();
         }, job);
         console.log("Name-> " + name);
     };
     count = count + 1;
};
console.log('Total jobs found:' + count);
this.click('input[value="Delete"]');

但是，当我运行这个脚本时，我总是得到：

Checking...row: 232...Test case 01...found
Job ID: 20180601054414
marked to remove...jobId:20180601054414
**Name-> null**
Total jobs found:80
waiting...10s

始终显示Name为null！因此querySelector找不到sel（ector）=＆gt;的click对象。 'input[value="' + job + '"]'。 由于“删除”单击正在显示错误消息“未选择任何作业”。

复选框的问题在哪里？？

先谢谢。
