继续示例 - 找不到 watir 元素 [英] continued example - cannot find watir element

问题描述

在 无法点击带有 watir 的 html 元素，我试图点击一个元素，它给了我下面的行:

我找不到您在上图中看到的三个下拉列表.我该怎么做 ?每次，下拉元素的 id 都会改变.

比如中间一段html代码是:

<select id="filtersJob6_intrinsic_enumOperator" name="filtersJob6_intrinsic_enumOperator" onchange="if(top.document.getElementById('filtersJob6_intrinsic_enumOperator').value=='isNull'||top.document.getElementById('intrinsic_enumOperator').='isNotNull'){top.document.getElementById('filtersJob6_intrinsic_operand1Container').style.display='none';}else{top.document.getElementById('filtersJob6_intrinsic_operand1Container').style.display='inline';}">;<option value="equals" selected="selected">equals</option><option value="notEqual">不等于</option><option value="isNull">未设置</option><option value="isNotNull">设置</option></选择></td>

id id="filtersJob6_intrinsic_enumOperator" 可以是任意数字 4,7,6,5 等.

如何让 watir 找到这个元素?

编辑 -

这是第一个下拉菜单的代码:<select id="filtersJob3_intrinsic_name" name="filtersJob3_intrinsic_name" onchange="var

解决方案

您可以在定位器中使用正则表达式:

browser.select_list(:id =>/filtersJob\d+_intrinsic_enumOperator/).select value_to_select

在这个例子中，正则表达式用正斜杠的开闭表示，原始字符串中的数字被替换为\d+，表示一个或多个数字".>

给定这个最小的 HTML 片段:

<option value="isNull">未设置</option><option value="isNotNull">设置</option></选择>
使用 select 选择基于文本的选项:
b.select_list(:id =>/filtersJob\d+_intrinsic_enumOperator/).select '已设置'
使用 select_value 根据 value 属性选择一个选项:
b.select_list(:id =>/filtersJob\d+_intrinsic_enumOperator/).select_value 'isNotNull'
In Cannot click html element with watir, i was trying to click an element which gives me the row below:



I am not able to find the three dropdown lists which you see in the image above.
How do I do it ? Each time, the id of the dropdown elements changes.

For example, the middle one html code is:
<td>
<select id="filtersJob6_intrinsic_enumOperator" name="filtersJob6_intrinsic_enumOperator" onchange="if(top.document.getElementById('filtersJob6_intrinsic_enumOperator').value=='isNull'||top.document.getElementById('filtersJob6_intrinsic_enumOperator').value=='isNotNull'){top.document.getElementById('filtersJob6_intrinsic_operand1Container').style.display='none';}else{top.document.getElementById('filtersJob6_intrinsic_operand1Container').style.display='inline';}">
<option value="equals" selected="selected">equals</option>
<option value="notEqual">not equals</option>
<option value="isNull">is not set</option>
<option value="isNotNull">is set</option>
</select>
</td>
The id id="filtersJob6_intrinsic_enumOperator" can have any number 4,7,6,5 etc.

How do I make the watir find this element ?

EDIT - 
Here is the code for the first dropdown:

<select id="filtersJob3_intrinsic_name" name="filtersJob3_intrinsic_name" onchange="var shown=0;top.document.getElementById('filtersJob3_intrinsic_operator').style.display='none';top.document.getElementById('filtersJob3_intrinsic_operand1').style.display='none';top.document.getElementById('filtersJob3_intrinsic_operand2').style.display='none';top.document.getElementById('filtersJob3_intrinsic_dateOperator').style.display='none';top.document.getElementById('filtersJob3_intrinsic_enumOperator').style.display='none';top.document.getElementById('filtersJob3_intrinsic_listOperator').style.display='none';top.document.getElementById('filtersJob3_intrinsic_uuidOperator').style.display='none';top.document.getElementById('filtersJob3_intrinsic_datehelp1').style.display='none';top.document.getElementById('filtersJob3_intrinsic_datehelp2').style.display='none';top.document.getElementById('filtersJob3_intrinsic_operand1abortStatus').style.display='none';top.document.getElementById('filtersJob3_intrinsic_operand1outcome').style.display='none';top.document.getElementById('filtersJob3_intrinsic_operand1priority').style.display='none';top.document.getElementById('filtersJob3_intrinsic_operand1status').style.display='none';top.document.getElementById('filtersJob3_intrinsic_operand1errorCode').style.display='none';if(top.document.getElementById('filtersJob3_intrinsic_name').value=='abortStatus'){shown=1;top.document.getElementById('filtersJob3_intrinsic_enumOperator').style.display='inline';top.document.getElementById('filtersJob3_intrinsic_operand1abortStatus').style.display='inline';top.document.getElementById('filtersJob3_intrinsic_operand2Container').style.display='none';}if(top.document.getElementById('filtersJob3_intrinsic_name').value=='outcome'){shown=1;top.document.getElementById('filtersJob3_intrinsic_enumOperator').style.display='inline';top.document.getElementById('filtersJob3_intrinsic_operand1outcome').style.display='inline';top.document.getElementById('filtersJob3_intrinsic_operand2Container').style.display='none';}if(top.document.getElementById('filtersJob3_intrinsic_name').value=='priority'){shown=1;top.document.getElementById('filtersJob3_intrinsic_enumOperator').style.display='inline';top.document.getElementById('filtersJob3_intrinsic_operand1priority').style.display='inline';top.document.getElementById('filtersJob3_intrinsic_operand2Container').style.display='none';}if(top.document.getElementById('filtersJob3_intrinsic_name').value=='status'){shown=1;top.document.getElementById('filtersJob3_intrinsic_enumOperator').style.display='inline';top.document.getElementById('filtersJob3_intrinsic_operand1status').style.display='inline';top.document.getElementById('filtersJob3_intrinsic_operand2Container').style.display='none';}if(top.document.getElementById('filtersJob3_intrinsic_name').value=='errorCode'){shown=1;top.document.getElementById('filtersJob3_intrinsic_enumOperator').style.display='inline';top.document.getElementById('filtersJob3_intrinsic_operand1errorCode').style.display='inline';top.document.getElementById('filtersJob3_intrinsic_operand2Container').style.display='none';}if(top.document.getElementById('filtersJob3_intrinsic_name').value=='jobId'){shown=1;top.document.getElementById('filtersJob3_intrinsic_uuidOperator').style.display='inline';top.document.getElementById('filtersJob3_intrinsic_operand1').style.display='inline';top.document.getElementById('filtersJob3_intrinsic_operand2Container').style.display='none';}if(top.document.getElementById('filtersJob3_intrinsic_name').value=='createTime'){shown=1;top.document.getElementById('filtersJob3_intrinsic_dateOperator').style.display='inline';top.document.getElementById('filtersJob3_intrinsic_operand1').style.display='inline';top.document.getElementById('filtersJob3_intrinsic_datehelp1').style.display='inline';top.document.getElementById('filtersJob3_intrinsic_operand2').style.display='inline';top.document.getElementById('filtersJob3_intrinsic_datehelp2').style.display='inline';}if(top.document.getElementById('filtersJob3_intrinsic_name').value=='finish'){shown=1;top.document.getElementById('filtersJob3_intrinsic_dateOperator').style.display='inline';top.document.getElementById('filtersJob3_intrinsic_operand1').style.display='inline';top.document.getElementById('filtersJob3_intrinsic_datehelp1').style.display='inline';top.document.getElementById('filtersJob3_intrinsic_operand2').style.display='inline';top.document.getElementById('filtersJob3_intrinsic_datehelp2').style.display='inline';}if(top.document.getElementById('filtersJob3_intrinsic_name').value=='modifyTime'){shown=1;top.document.getElementById('filtersJob3_intrinsic_dateOperator').style.display='inline';top.document.getElementById('filtersJob3_intrinsic_operand1').style.display='inline';top.document.getElementById('filtersJob3_intrinsic_datehelp1').style.display='inline';top.document.getElementById('filtersJob3_intrinsic_operand2').style.display='inline';top.document.getElementById('filtersJob3_intrinsic_datehelp2').style.display='inline';}if(top.document.getElementById('filtersJ

解决方案
You can use a regular expression in your locator:
browser.select_list(:id => /filtersJob\d+_intrinsic_enumOperator/).select value_to_select
In this example, the regular expression is denoted by opening and closing  forward slashes, and the digit within the original string is replaced with \d+, which means "one or more digits".

EDIT:

Given this minimal HTML snippet:
<select id="filtersJob6_intrinsic_enumOperator">
  <option value="isNull">is not set</option>
  <option value="isNotNull">is set</option>
</select>
Use select to choose on option based on text:
b.select_list(:id => /filtersJob\d+_intrinsic_enumOperator/).select 'is set'
Use select_value to choose an option based on the value attribute:
b.select_list(:id => /filtersJob\d+_intrinsic_enumOperator/).select_value 'isNotNull'
