如何将表单中的数据发送到类并将其可视化？

问题描述 投票：-1回答：1

我需要传递从表单收集的一些数据并将其传递给类并将其可视化，我发送数据时遇到问题，因为我无法接收它

        class F1{

            constructor(num,clien,direc,nife,nifd,div,sub,iva){
                this.num = num
                this.clien = clien
                this.direc = direc
                this.nife = nife
                this.nifd = nifd
                this.div = div
                this.sub = sub
                this.iva = iva
            }
        }
   <form name="formu" id="formu">
        num:
        <input type="text" name="num" value=""><br><br>
        clien:
        <input type="text" name="clien" value=""><br><br>
        direc:
        <input type="text" name="direc" value=""><br><br>
        NIFe:
        <input type="text" name="nife" value=""><br><br>
        NIFd:
        <input type="text" name="nifd" value=""><br><br>
        div:
        <input type="text" name="div" value=""><br><br>
        sub:
        <input type="text" name="sub" value=""><br><br>
        iva:
        <input type="text" name="iva" value=""><br><br>
        <input type="submit" value="Enviar">
    </form>

谢谢

如果我理解你的问题，你可以尝试这个代码：

我用二传手和吸气剂; document.forms。有关更多信息，请阅读：

W3Schools的：setter and getter
