continued example - cannot find watir element

问题

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

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'
