概述：【jQWidgets】API 笔记

$("#jqxgrid").jqxGrid({  
      theme: 'energyblue',  
      altrows: true,//行间底色区分  
      width: 500,  
      sortable: true,//设置可排序  
      pageable: true,//设置可分页  
      pagesize: 10,//设置默认页数  
      pagesizeoptions: ['10', '20', '30'],//设置分页数  
      columnsresize: true,//列可适应调整  
      clipboard: false,//屏蔽jqx的复制功能  
      enablebrowserselection: true,//允许使用浏览器选择内容功能  
      editable: true  
      source: dataAdapter,//数据源  
      columns: [{  
          text: 'First Name',  
          datafield: 'firstname',  
          width: 100  
      }]//列字段定义  
  });

常用：

//jqxGrid的复制功能 Code example
$('#jqxGrid').jqxGrid({ clipboard: false});
var clipboard = $('#jqxGrid').jqxGrid('clipboard');

//允许选择浏览器的文本内容Code example
$('#jqxGrid').jqxGrid({ enablebrowserselection: true});
var enablebrowserselection = $('#jqxGrid').jqxGrid('enablebrowserselection');

//设置列间距可调
$('#jqxGrid').jqxGrid({ columnsresize: false});

//获取是否可调值
var columnsresize = $('#jqxGrid').jqxGrid('columnsresize');

//数据绑定完成后事件,放在grid之前
$("#jqxGrid").on("bindingcomplete", function (event) {// your code here.});
$("#jqxgrid").jqxGrid({});

////获取整个数据行数
var rows = $('#jqxGrid').jqxGrid('getrows');
var data = $('#jqxGrid').jqxGrid('getrowdata', 0);

//设置某一行选中

$('#jqxGrid').jqxGrid('selectrow', 10);

//获取选中行的index

var rowindex = $('#jqxGrid').jqxGrid('getselectedrowindex');

//获取选中行其中一列的相关数据

var cell = $('#jqxgrid').jqxGrid('getselectedcell');
if (cell) {
alert("Row: " + cell.rowindex + ", Column: " + cell.datafield);
}

//jsfiddle.net/jqwidgets/vFJ35/

//jsfiddle.net/jqwidgets/kBNWp/

//数据绑定后函数

var dataAdapter = new $.jqx.dataAdapter(source, {
                downloadComplete: function (data, status, xhr) { },
                loadComplete: function (data) { },
                loadError: function (xhr, status, error) { }
            });

行双击事件
$('#jqxGrid').on('rowdoubleclick', function (event)
{
var args = event.args;
// row's bound index.
var boundIndex = args.rowindex;
// row's visible index.
var visibleIndex = args.visibleindex;
// right click.
var rightclick = args.rightclick;
// original event.
var ev = args.originalEvent;
});

//jsfiddle.net/jqwidgets/CgvvZ/

编辑触发事件
$("#jqxgrid").on('cellbeginedit', function (event) {
var args = event.args;
$("#cellbegineditevent").text("Event Type: cellbeginedit, Column: " + args.datafield + ", Row: " + (1 + args.rowindex) + ", Value: " + args.value);
});
$("#jqxgrid").on('cellendedit', function (event) {
var args = event.args;
$("#cellendeditevent").text("Event Type: cellendedit, Column: " + args.datafield + ", Row: " + (1 + args.rowindex) + ", Value: " + args.value);
});

列验证
columns:[
{text:'日期',dataField:'DT',width:'50%',validation:function(){
if(value==''){

return{message:'日期必须填写',result:false};
}
return true;
}
}
]

编辑框
$('#editor').jqxEditor({

                height: "400px",
                width: '800px'theme: 'energyblue',		theme: 'energyblue',    		tools: 'bold italic underline right link'//为空时无工具条
});

Ajax读取后，调用


function bindData(name,da,field,col){  
                        $("#"+name).jqxGrid({  
                                width : '100%',  
                                height : '100%',  
                                theme:theme,  
                                showtoolbar: false,  
                                source : {  
                                        localdata : da,  
                                        datatype : "array",  
                                        datafields : field  
                                },  
                                sortable: true,  
                                pageable : false,  
                                editable : true,  
                                columns :col  
                        });  
                }
