| function getBlockByValue() { | |
| var levels = document.getElementsByClassName('level'); | |
| var length = levels.length; | |
| var ret = []; | |
| for (var i = 0; i < length; i++) { | |
| var level = levels[i]; | |
| if (level.innerHTML == '[FAIL]' || level.innerHTML == '[PASS]') { | |
| ret.push(level); | |
| } | |
| } | |
| return ret; | |
| } |
In this example, you get a element like <td class="level">[FAIL]</td>, here the level will appear in every row of the table, cannot used to determine the location, but the value [FAIL] or [PASS] only appear once in the whole page.
