Question

出于某种原因，我的网格是空白的，没有行（甚至没有空行），没有导航图标，也没有编辑图标。我正在使用一些加载项功能，例如自动填充字段（在网格内）和字体大小调整脚本，所以我的脚本有点长。该页面正在从我的函数页面接收格式正确的响应，它似乎与我的jsonReader设置相匹配，但它没有用它填充网格。这是我在页面中的JSON格式响应：

{"page":"1",
"total":1,
"records":"4",
"rows":[{"DetailID":"1","Quantity":"2","TaskName":"Differencial With Housing","UnitPrice":"335.00","ExtendedPrice":"670.00"}, {"DetailID":"2","Quantity":"1","TaskName":"Left axel seal","UnitPrice":"15.00","ExtendedPrice":"15.00"},{"DetailID":"3","Quantity":"1","TaskName":"Upper and Lower Bearings","UnitPrice":"55.00","ExtendedPrice":"55.00"}, {"DetailID":"5","Quantity":"1","TaskName":"Fluids","UnitPrice":"45.00","ExtendedPrice":"45.00"}]}

这是我的网格脚本：

<script>    
    function autocomplete_element(value, options) {
      var $ac = $('<input type="text"/>');
      $ac.val(value);
      $ac.autocomplete({source: "autocomplete.php?method=fnAutocomplete"});
      return $ac;
    } 
    function autocomplete_value(elem, op, value) {
      if (op == "set") {
        $(elem).val(value);
      }
      return $(elem).val();
    }
        $(document).ready(function()
            {
                $('#filter').jqm();
                var selectedRow = 0;                
                $("#list").jqGrid(
                {
                    url:'managegrid.php',
                    datatype: 'json',
                    colNames:['DetailID', 'ProjectID','Qty.','Description','Unit Price','Total Cost'],
                    colModel :[

                        {name:'ExtendedPrice', index:'ExtendedPrice', editable:false, width:100, align:'right'}
                    ],
                    onSelectRow: function(id){
                      if(DetailID && DetailID!==mkinline){
                        jQuery('#list').saveRow(mkinline);
                        jQuery('#list').editRow(DetailID,true);
                        mkinline=DetailID;
                      }

        $("#t_list").html(a.USERDATA.MSG);
        resetForm();
        return true;
    }   function resetForm()
    {
      window.location.reload(false);
    }
</script>

我一直试图在整个周末想出这个，这让我发疯，所以任何帮助都会受到赞赏。

您应该添加代码行

jQuery("#list").jqGrid("navGrid", '#pager',
    {add: false, edit: false, del: false, search: false, refresh: false});

直接在调用inlineNav之前。

更新：您的代码也存在许多其他问题。例如，您应该从代码中删除jsonReader选项，因为它包含错误的属性值（例如root: "ROWS"而不是root: "rows"，这是默认值并且可以删除）。您可以考虑使用jsonReader: { id: 'DetailID' }将DetailID的值用作rowid，并在编辑期间使用DetailID代替id。我建议您在使用前定义所有变量（例如，请参阅mkinline和DetailID）。
