我在表上有一个复选框,选中后,我想将填充表中数据的值追加到数组中(下面代码中的tableData.element.link)。
我已经有一个toggleRow
方法,该方法在单击复选框时会被调用,但是如何在单击复选框时将匹配的tableData.element.link
附加到数组中?即如何获取被单击的复选框行的索引,以便可以从tableData数组中获取正确的值?
componentDidMount() {
const _self = this;
fetch(config.api.urlFor('xxx'))
.then((response) => response.json())
.then((data) => {
const tableContent = [];
data.array.forEach(element => {
tableContent.push({
date: element.date,
title: element.title,
link: <Link to='' onClick={(e)=> {e.preventDefault(); this.getPreauthorizedLink(element.link)}}>Report</Link>
});
})
this.tableData = tableContent;
this.setState({reportJSON: tableContent || [], tableIsBusy: false})
})
.catch((err) => _self.setState({tableIsBusy: false }));
}
toggleRow(name, id) {
const newSelected = Object.assign({}, this.state.selected);
let awsFileKeys = [];
if(newSelected[name]){
delete newSelected[name]
}else {
newSelected[name] = !this.state.selected[name];
}
this.setState({
selected: newSelected,
selectAll: 2
});
awsFileKeys.push(this.tableData.element.link[id]);
console.log(awsFileKeys);
}
答案 0 :(得分:0)
我完成此操作的方法实际上是在将AWS文件密钥分配给每个复选框之后查看复选框的值。然后,我从所选项目数组中取出所有AWS文件密钥,并将它们放在新数组中:
toggleSelectAll() {
let newSelected = {};
let newFileKeys = [];
if (this.state.selectAll === 0) {
this.state.reportJSON.forEach(x => {
newSelected[x.linkRaw] = true;
});
}
this.setState({
selected: newSelected,
selectAll: this.state.selectAll === 0 ? 1 : 0
})
for(let item in Object.keys(this.state.selected)){
newFileKeys.push(this.state.selected[item]);
}
this.state.awsFileKeys = newFileKeys;
}
