如何在jqgrid PHP中进行计算

Question

I have a problem

I have 3 column in jqGrid .

Let's say it A , B , C .

When I insert data, I only have to fill data for column A and B .

Column C is automatically inserted with the value of A + B .

I'm using jqGrid for PHP and I'm using form to insert the data

Is there a way on how to assign and insert the value of C ?

Answer 1

You can calculate the value of C with a custom formatter without PHP

<table id="#grid-table"></table>

jQuery("#grid-table").jqGrid({
  colNames: ['id', 'A', 'B', 'C'],
  colModel: [
    {name: 'id', key: true, index: 'id', hidden: true},
    {name: 'A', index: 'A'},
    {name: 'B', index: 'B'},
    {name: 'C', formatter: function(cellvalue, options, rowData) {
      return rowData.A + rowData.B;
    }}
  ]
})
