- ag-grid常用方法
//获取选中数据
var rows=gridOptions.api.getSelectedRows();
//全选包含隐藏的行
gridOptions.api.selectAll();
//反选
gridOptions.api.deselectAll();
//根据筛选条件选中行
gridOptions.api.selectAllFiltered();
//根据筛选条件选反行
gridOptions.api.deselectAllFiltered();
//表格宽度自适应
gridOptions.api.sizeColumnsToFit();
//获取第三行对象
var rowNode=gridOptions.api.getRowNode(2);
var x=JSON.stringify(rowNode.data);
//获取当前焦点的单元格
var cell=gridOptions.api.tabToNextCell();
//设置name列的2行获得焦点
gridOptions.api.setFocusedCell(1,'name');
//清除单元格焦点
gridOptions.api.clearFocusedCell();
//设置下一个单元格为当前焦点
gridOptions.api.tabToNextCell();
//设置上一个单元格为当前焦点
gridOptions.api.tabToPreviousCell();
//获取选中的数据
var selRows= this.gridApi.getSelectedRows();
//注意调用updateRowData方法并不会更新vue的data
this.gridApi.updateRowData({remove: selRows});//更新行:删除选中数据(不删vue的data)
//正确的删除方法是这样的
this.rowData = this.rowData.filter(item =>{
return selRows.filter(m=>m.title===item.title).length<=0
} );
//动态设置行高 重新设置为100px
function setHeight()
{
ag.gridOptions.rowHeight=100;
ag.gridOptions.api.resetRowHeights();
}
//更新第一行数据 rowData为行数据
rowData[0].name = 'good';
var params = {
force: true
};
gridOptions.api.refreshCells(params);//更新单元格数据

- ag-grid常用方法和属性
this.gridCnDiag.api.exportDataAsExcel(null);//导出Excel
let ct = this.gridOptions.api.getModel().getRowCount(); //ag-grid总条数
const cell = gridObj.api.getFocusedCell() as any;//获得选中单元格对象
if (cell) {
const field = cell.column.colDef.field;//字段名称
let rowIndex = cell.rowIndex;
}
//遍历ag-grid
this.gridObj.api.forEachNode((node) => {
if (previousCell.rowIndex - 1 === node.rowIndex) {
node.setSelected(true);
}
});
let rowData = this.gridObj.api.getRowNode(rowIndex).data;//获得指定行内容
let rowselectData = this.gridObj.api.getDisplayedRowAtIndex(deleteRow.rowIndex).data; //获得指定行内容
let rowArr = this.gridObj.api.getSelectedRows(); //获得所有选择行
let nodeArr: RowNode[] = this.gridBaby.api.getSelectedNodes();//获取当前表格的选中node
this.gridObj.api.updateRowData({
add: rowData
});
this.gridObj.api.getDisplayedRowAtIndex(rowIndex).setSelected(true, null);//设置或取消选中行颜色
this.gridObj.api.setFocusedCell(rowIndex, 'name');//下一个单元格设置焦点
this.gridObj.api.clearFocusedCell();//取消选择焦点
that.gridObj.api.ensureNodeVisible(rowNode);//节点可见？
this.gridObj.columnApi.setColumnsVisible(['name','age'], true);//显示/隐藏列 （true显示，false隐藏）
{
this.gridObj.columnApi.getColumn("name").getColDef().headerName = '新名称'//改标题
this.gridObj.columnApi.setColumnWidth("name", 53);//设置列宽度
this.gridObj.api.refreshHeader();
}
this.gridObj.api.ensureColIndexVisible('列英文名');//横滚动条跟随焦点跳转
that.gridObj.api.startEditingCell({
rowIndex: rowIndex,
colKey: '列英文名'
});//下一个单元格设置为可编辑
this.gridObj.api.stopEditing();//结束编辑状态
- 获得ag-grid所有列
/**
* 获得ag-grid所有列
* @param gridObj
* @returns
*/
public static GetGridColumns(gridObj: any) {
let sortColArr = [];//所有列集合
for (let index = 0; index < gridObj.columnDefs.length; index++) {
const element = gridObj.columnDefs[index];
if (element['field'] != 'RowNo' && element['editable'] == true && !element['hide']) {
sortColArr.push(element['field']);
}
}
return sortColArr;
}
- 文本框支持放入焦点选择全部
let inputList = document.querySelectorAll('input');
for (let index = 0; index < inputList.length; index++) {
inputList[index].onfocus = this.selectValue;//onmouseover
}
//全选文本 2021-9-24
selectValue(e) {
e.currentTarget.select();
}
- 动态追加列
<button @click='btnShowTable'>动态追加列</button>
/**
* 动态加载ag-grid列
*/
btnShowTable() {
let that = this as any;
let defaultCols = [//表头
{
headerName: '备注',
field: 'REMARK',
width: 100,
editable: false,//单元格是否可编辑
cellRenderer: (params) => {
let txt = params.data.REMARK;
txt = txt ? txt : '';
return `<div title='${txt}'>${txt}</div>`;
},
},
];
if (this.isShowMore) {
let tempCol = `{
"headerName": "标题",
"field": "字段",
"width": 150,
"editable":true
}`;
defaultCols.push(colObj);
}
this.gridOptions.api.setColumnDefs(defaultCols);
}
public get gridOptions(): GridOptions {
const that = this;
return {
headerHeight: 30,// 表头高度
rowHeight: 30,// 行高
columnDefs: [],//列定义 一定是空对象！！！
showToolPanel: false, // 显示工具栏
singleClickEdit: true,//【单击编辑单元格】
enableSorting: true,//允许排序
suppressRowClickSelection: true,
enableColResize: true,//允许调整列宽
suppressLoadingOverlay: true,// 去掉表格加载数据提示
suppressNoRowsOverlay: true,// 去掉表格无数据提示
suppressDragLeaveHidesColumns: true,//防止拖动的时候隐藏表格列
suppressContextMenu: true,// 阻止表格的右键菜单
defaultColDef: {
suppressMenu: true,//隐藏表头菜单
},
onRowClicked(params) {
params.node.setSelected(!params.node.isSelected());//js选择行
},
rowSelection: 'single',//只允许多选中 multiple
onCellClicked: async function (ent) {//单元点击事件
that.selectRow = JSON.parse(JSON.stringify(ent.data));
if (that.selectRow && Object.keys(that.selectRow).includes('QC_TYPE')) {
that.selectRow['QC_TYPE'] = that.selectRow['QC_TYPE'].toString();
}
let itemId = ent.data['ITEM_ID'];
let type = ent.event.srcElement['innerText'];
let isA = ent.event.srcElement['localName'] === 'a';
},
};
}
- 需求：选中一行时执行特定任务。先是用 onRowSelected 很坑，选中行后里面代码会执行两次！！！换成onRowClicked问题解决。
- 怎么指定列排序：
grid1.columnApi.getColumn("SORT_CODE").setSortedAt(true) - 按参数记住的列顺序重新显示
let currCol = this.gridOptions.columnApi.getColumnState();
let newCol = [];
for(.......){
newCol.push(...)
}
that.gridOptions.columnApi.setColumnState(newCol);
