jqxGrid source CRUD

jqxGrid source 的增删改 API介绍

jqxGrid source addrow

/**
* jqxGrid  source 增加一列
* @param rowid  增加列的id
* @param rowdata 增加列的数据
* @param position  addrow通过position可以接受一个函数(function)
* @param commit   true or false 来判断是否增加此列
*/
addrow: function (rowid, rowdata, position, commit) {
       // synchronize with the server - send insert command
       // call commit with parameter true if the synchronization with the server is successful 
       // and with parameter false if the synchronization failed.
       // you can pass additional argument to the commit callback which represents the new ID if it is generated from a DB.
       position() //调用下面的fun方法
       commit(true);
},
按钮触发
 // create new row.
$("#addrowbutton").on('click', function () {
       var datarow = generaterow();
       function fun(){todo}
       /**
       * 通过addrow匹配source中的addrow方法，null不传，则默认接收rowId，datarow，row数据，fun，方法
       * @type {*|{scripts, deps}|jQuery}
       */
       var commit = $("#grid").jqxGrid('addrow', null, datarow，fun);
 });

jqxGrid source deleterow

通过jqxGrid source删除一行数据，通常需要选择一行，然后获取rowid，在进行删除，其余跟addrow相同。

 deleterow: function (rowid, commit) {
      // synchronize with the server - send delete command
      // call commit with parameter true if the synchronization with the server is successful 
      //and with parameter false if the synchronization failed.
      commit(true);
 },

按钮触发
// delete row.
$("#deleterowbutton").on('click', function () {
       //获取选中行
       var selectedrowindex = $("#grid").jqxGrid('getselectedrowindex');
       //获取总共有几行
       var rowscount = $("#grid").jqxGrid('getdatainformation').rowscount;
       if (selectedrowindex >= 0 && selectedrowindex < rowscount) {
           //获取选中行的id
           var id = $("#grid").jqxGrid('getrowid', selectedrowindex);
           ar commit = $("#grid").jqxGrid('deleterow', id);
        }
});

jqxGrid source update

jqxGrid source update与addrow大致相同，只不过取消了回调函数

updaterow: function (rowid, newdata, commit) {
     // synchronize with the server - send update command
     // call commit with parameter true if the synchronization with the server is successful 
     // and with parameter false if the synchronization failed.
     commit(true);
}
