html表单 <input id="txtPipeRowName" style="width:150px;"> <input id="txtPipeName" style="width:150px;"> easyUi的Combobox:
// 一层Combo var srmCombx = $("#txtShouName")combobox({ loader:function(param,success,error){ $ajax({ url: '${CTX_ROOT}/TEquipmentsController?method=getEquipmentByParId&id='+selectSgId+'', dataType: 'json', success: function(data){ dataunshift({equipmentid:'',equipmentname:'全部'}); success(data); }, error: function(){ errorapply(this, arguments); } }); }, onSelect:function(record){ //onSelect 用户点击时触发的事件 在此的意义在于，用户点击一级后自动二级combobox piperowCombxcombobox({ loader:function(param,success,error){ $ajax({ url: '${CTX_ROOT}/TEquipmentsController?method=getEquipmentByParId&id='+$("#txtShouName")combobox("getValue")+'', dataType: 'json', success: function(data){ dataunshift({equipmentid:'',equipmentname:'全部'}); success(data); }, error: function(){ errorapply(this, arguments); } }); }, onSelect:function(record){ //这里也使用了onSelect事件，在二级combobox被用户点击时触发三级combobox pipeCombxcombobox({ loader:function(param,success,error){ $ajax({ url: '${CTX_ROOT}/TEquipmentsController?method=getEquipmentByParId&id='+$("#txtPipeRowName")combobox("getValue")+'', dataType: 'json', success: function(data){ dataunshift({equipmentid:'',equipmentname:'全部'}); success(data); }, error: function(){ errorapply(this, arguments); } }); }, valueField: 'equipmentid', textField: 'equipmentname', value:'', editable:false }); }, onLoadSuccess:function(){ //清空三级下拉框 就是成功加载完触发的事件 当一级combobox改变时，二级和三级就需要清空 pipeCombxcombobox("clear"); pipeCombxcombobox('setValue', '全部'); //给combobox下拉框设置一个值，否则为空不好看 }, valueField: 'equipmentid', textField: 'equipmentname', value:'', editable:false })combobox("clear"); //清空二级下拉框 }, valueField: 'equipmentid', textField: 'equipmentname', value:'', editable:false }); /*******************************/ //下面的俩个是组件， // 二层Combo var piperowCombx = $("#txtPipeRowName")combobox({ loader:function(param,success,error){ $ajax({ url: '${CTX_ROOT}/TEquipmentsController?method=getEquipmentByParId&id='+$("#txtShouName")combobox("getValue")+'', dataType: 'json', success: function(data){ dataunshift({equipmentid:'',equipmentname:'全部'}); success(data); }, error: function(){ errorapply(this, arguments); } }); }, valueField: 'equipmentid', textField: 'equipmentname', value:'', editable:false }); //三层Combo var pipeCombx=$("#txtPipeName")combobox({ loader:function(param,success,error){ $ajax({ url: '${CTX_ROOT}/TEquipmentsController?method=getEquipmentByParId&id='+$("#txtPipeRowName")combobox("getValue")+'', dataType: 'json', success: function(data){ dataunshift({equipmentid:'',equipmentname:'全部'}); success(data); }, error: function(){ errorapply(this, arguments); } }); }, valueField: 'equipmentid', textField: 'equipmentname', value:'', editable:false });以上就是本文的全部内容，希望对大家的学习有所帮助，也希望大家多多支持wanshiok.com。
