如果 function 在数据表上

Question

    function sortfuction(selected) {
            var id = selected.value;
                if (id=0) {
                    $('#password-table').DataTable( {
                    "destroy": true,
                    "paging": false,
                    "searching":false,
                    "order": [[ id, "asc" ],]
                } );
                }
                }else{
                    $('#password-table').DataTable( {
                    "destroy": true,
                    "paging": false,
                    "searching":false,
                    "order": [[ id, "dsc" ],]
                }
        </script>
   <table id="password-table" class=" row-border" style="width:100%">
        <thead>
    <select id="selectorID" onchange="sortfuction(this)">
        <option value="1" >Count</option>
        <option value="0">ABC</option>
    </select>

Having this code, I want to be able to sort tables depending on what value is chosen on Select element. For instance, if ABC is chosen, I want my first datatable column to be sorted in ascending order, while if chosen Cound, I want my second column to be sorted descending order. At this point console returns

Unexpected token 'else'

Answer 1

You have an extra } before your else statement, just delete it. But you're also missing an ) and another } after your else and another } to close the function. Also your if statement needs a double equals or triple equals == to test for equalliing a value otherwise it's just an assignment.

Also a quick look at the docs show it should be 'desc' not 'dsc' to sort descending. I have updated the code

so

function sortfuction(selected) {
        var id = selected.value;
            if (id==0) {
                $('#password-table').DataTable( {
                "destroy": true,
                "paging": false,
                "searching":false,
                "order": [[ id, "asc" ]]
            } );

            }else{
                $('#password-table').DataTable( {
                "destroy": true,
                "paging": false,
                "searching":false,
                "order": [[ id, "desc" ]]
            })
            }
  }
