对js对象执行循环,然后使用map方法代替一次又一次调用组件
Performing loop on js objects and then use map method instead of calling component again and again
在 React 中需要帮助……我将复杂的 xml 文件转换为 js 对象格式。转换xml文件后,js对象存储在ress变量中,如图所示。我们将不同的部分转录本存储在不同的变量中。有没有什么办法可以使用循环来做到这一点,并在每次迭代中用正则表达式将其拆分。所以我可以很容易地使用 map 方法,而不是为每个部分转录本一次又一次地调用组件。
parser.parseString(xmlToParse, function (err, result) {
console.log(result)
ress = result;
});
var regex=/ (?=\w+:)/g
var str0=ress.ROOT.record[0].index[0].point[0].partial_transcript[0];
var ptr0=str0.split(regex)

你可以试试这个:
parser.parseString(xmlToParse, function (err, result) {
console.log(result)
ress = result;
});
var regex=/ (?=\w+:)/g
//this object will contain all the variabels with the numbers and the names
const object = {}
//easier to read
const ress = ress.ROOT.record[0].index[0].point
//while loop will do the work
let i = 0
while(i < ress.length) {
const str = ress[i].partial_transcript[0];
object[`ptr`+i] = str.split(regex)
i++
}
