Javascript 使用ag栅格在未定义字段上编辑列

我已经为如下列定义配置了ag网格

    {
        headerName: 'Model Level',
        field: 'ModelLevelTimeSeries.Id.Value',
        editable: false,
        cellRendererFramework: RenderEntityComponent,
        cellStyle: { textAlign: "center" },
        suppressSizeToFit: true,
    }

基本上，后端的字段可以返回null

"ModelLevelTimeSeries": {
        "Id": null
    }

或

当我编辑单元格值时，对于

agInit

方法中的

params.value

，它返回

null

。
我使用的是“ag网格”：“^17.0.0”，

“ag grid angular”：“^17.0.0”。

只需在列定义中添加CellrNoder函数即可

cellRenderer: params => params.value ? params.value : ''

现在就是这样

   {
        headerName: 'Model Level',
        field: 'ModelLevelTimeSeries.Id.Value',
        editable: false,
        //add below line
        cellRenderer: params => params.value ? params.value : ''
        cellRendererFramework: RenderEntityComponent,
        cellStyle: { textAlign: "center" },
        suppressSizeToFit: true,
    }

您可以将值设置器用于您的文件

{
  headerName: 'Model Level',
  field: 'ModelLevelTimeSeries.Id.Value',
  editable: false,
  cellRendererFramework: RenderEntityComponent,
  cellStyle: { textAlign: "center" },
  suppressSizeToFit: true,

  valueSetter: function(params: any){
     if (params.oldValue !== params.newValue) {
         params.data[params.colDef.field] = (params.newValue) !== "" ? params.newValue.toUpperCase() : "";
         return true;
     } 
     else {
         return false;
     }
  }
}

根据我的经验，如果字段为.a.nested.key，则在valueSetter中使用params.data[params.colDef.field]将不起作用，因为params.colDef.field只返回类似“ModelLevelTimeSeries.Id.Value”的字符串

目前，我依靠lodash的set（）在valueSetter中实现这一点：

import * as set from 'lodash/set'

changeDetectValueSetter (params) {
  if (params.oldValue !== params.newValue) {
    set(params.data, params.colDef.field, params.newValue) // had to use lodash set, because params.colDef.field is a string representation of a nested object key
    // params.data.instruction.billingrecord.invoice_number = params.newValue // could have done this, but it's fixed for that field.
    // params.data[params.colDef.field] = params.newValue // this does not work at all if the field is.a.nested.key
    return true
  } else {
    return false
  }
},

---

这对你有用吗？？

import * as set from 'lodash/set'

changeDetectValueSetter (params) {
  if (params.oldValue !== params.newValue) {
    set(params.data, params.colDef.field, params.newValue) // had to use lodash set, because params.colDef.field is a string representation of a nested object key
    // params.data.instruction.billingrecord.invoice_number = params.newValue // could have done this, but it's fixed for that field.
    // params.data[params.colDef.field] = params.newValue // this does not work at all if the field is.a.nested.key
    return true
  } else {
    return false
  }
},
