In order to explain the design of automatic scoring table based on multi-level indicators, as well as related indicators assessment scoring business, wrote the demo code for developers to reference, mainly related to table dynamic operation technology and algorithm practice.

1. HTML DOM Table Object Operation 1.1. Insert a row

Using the HTML DOM insertRow () method, the InsertRow (index) method is used to insert a new row at the specified position in the table.

If index equals the number of rows in the table, the new row is appended to the end of the table.

1.2. Inserting cells

Using the HTML DOM InsertCell () method, the InsertCell () method is used to insert an empty element at the specified location on one line of the HTML table <td> .
  
If index equals the number of cells in the row, the new cell is appended to the end of the row.

As shown in the table above, if a merged cell exists, inserting a cell position calculation will be a pain point, in this case the row is merged, the index in InsertCell (index) in the first row after the merged cell is postponed by 1 ... When you change to the next row in the range of merged cells, index counts from 0.

1.3. Set the HTML DOM TableCell object

The TableCell object properties used in this example are:
RowSpan, Sets or returns the number of rows that a cell can span.
InnerHTML, you can set or return the HTML between the opening and closing tags of a cell.

1.4. Insert rows First, then insert cells

Using the script to dynamically create the table procedure is as follows (as this example resolves):
  
(1) Based on a table that is currently written in HTML

<table id="myTable" border="1"></table>

(2) With this table as the root, insert "All" line by line the number of rows required

All, refers to the merged cells by row, one-time insert rowspan number of rows.

  for (var j=0;j<rowspan;j++){    //rownum是当前行数,‘myTable‘是已经在HTML中写好的table    var tmpRow=document.getElementById(‘myTable‘).insertRow(rownum);    //为行定义ID    "rowid" + rownum;    rownum =  1;  }

(3) Insert cells by row, and initialize

  tmpcell_1 = document.getElementById("rowid" + rownum).insertCell(1);  tmpcell_2 = document.getElementById("rowid" + rownum).insertCell(2);  //通过innerHTML初始化输入框,用于输入分数  tmpcell_2.innerHTML="<input name=\"grate\" type=\"text\" id=\"grate\" maxlength=\"3\" rule=\"""\">";
2. Scoring data rule validation 2.1. Compare data first after sorting

Use the sort () method to sort the elements of the array.
  
The numeric sort must use a sort function [1], as shown in the following code (omitted from the demo code in this article).
  

<script type="Text/javascript"> function sortnumber(A, B){returnA-B}vararr =New Array(6) arr[0] ="Ten"arr[1] ="5"arr[2] ="Max"arr[3] ="very"arr[4] ="+"arr[5] ="1"document.write (arr +"<br/>") document.write (Arr.sort (sortnumber)) </script>
2.2. Sorting by groups

The grouping rule is set on the input custom attribute, which defines the attribute as rule.

    grateObject = document.getElementsByName("grate");    len = grateObject.length;    rule[0] = grateObject[0].getAttribute("rule");
3. Demo Code

Demo effect as shown, first click on the button "test multi-level indicator display", show the indicator evaluation table, fill in the score (for example, all 5 points), and then click the button "test reading scoring data and scoring rules verification", two times "the same value."
