What to do: Gets the total number of rows in the table, the number of columns, gets the text value of a cell, and deletes a row "If a Delete button is provided behind each line"
Case:
HTML code :
<meta http-equiv= "Content-type" content= "Text/html;charset=utf-8" >
<body>
<script type= "Text/javascript" >
function DeleteRow (TableID, obj) {//parameter is table ID, trigger object
To get the line number of the trigger object, the number of parentelement depends on the first few sub-items of the Trigger object TR, INPUT=>TD=>TR, so Parentelement has two
var rowIndex = Obj.parentElement.parentElement.rowIndex;
var table = document.getElementById (TableID). DeleteRow (RowIndex);
Alert ("Are you sure you want to delete it?") ")
Obj.parentElement.parentElement.parentElement.deleteRow (RowIndex); Re-simplification: omitting TableID parameters
}
</script>

Explanation: Text_to_be_present_in_element is actually a class, and because of the addition of the __call__ method, its instances can also be called
Function: Checks whether the text on the specified element matches the expected
Check whether the idea of success
1. Delete the last line, that is, the serial number is ' 4 ', so as long as the entire table to check if there is still ' 4 ', if the return false, the deletion succeeds, if the other cell contents in the table does not contain ' 4 '
"If the contents of other cells contain ' 4 ' and return true, it is obvious that the check result is incorrect, so the expected value to be checked here must be unique in the table, such as with an ID"
2. Check that the ordinal of the last row in the table is ' 4 ', if not, the deletion succeeds
3. Check the number of rows in the table to determine
