javascript – React JS：如何从this.state.data中正确删除一个项目,其中数据是一组对象

基于通过 @L_944_0@调用检索的数据数组,我有一个组件生成一行数据行(< tr>等).一切都适用于编辑和添加数据,但是我无法确定如何使数组的不同副本(包含对象的不同副本 – 通过val,而不是ref),以便当我删除指定的行数据,适用的行从表中删除.

目前,由于包含的对象是ref,即使我做了一个数组的副本,我的表也删除了最后一行(即使在AJAX调用中行索引和数据都被正确引用和删除).

handleRowdelete: function(rowIdX) {
     // Correct row 
     var row = this.state.data[rowIdx];

     // This makes a new array,but the contained objects are still by ref
     var rows = this.state.data.slice();

     // This contains the proper row that will be deleted. If this array is set to data,the table is updated to reflect just the one row - as expected.
     var throwout = rows.splice(rowIdx,1);
     console.log(throwout);

     // Whether I set via the React.addons: 
     var newState = React.addons.update(this.state,{
         data: { $set: rows }
     });
     this.setState(newStatE);

     // Or just set the state again via this.setState(...)
     //this.setState({data: rows,add: falsE});

     // It always just removes the last row in the component render
     // Even though the proper row gets deleted following in AJAX call
     $.ajax({
     ...
},...

我理解React不能做出正确的差异,所以渲染没有被触发,所以你能告诉我应该如何处理？

var Grid = React.createClass({
    propTypes: {
        data: React.PropTypes.array.isrequired,onCellChange: React.PropTypes.func.isrequired,onRowCommit: React.PropTypes.func.isrequired
    },render: function() {
        var rows = this.props.data.map(function(rowData,indeX) {
            return <Row key={index} data={rowData} onCellChange={this.props.onCellChange.bind(null,indeX)} onRowCommit={this.props.onRowCommit.bind(null,indeX)} onRowdelete={this.props.onRowdelete.bind(null,indeX)} />;
        },this);
