JS实现水平遍历和嵌套递归操作示例

let p1 = false,
p2 = true,
p3 = false；
let test = function() {
    if (p1) {
      return '终止1';
    } else {
      return function() {
        if (p2) {
          return '终止2'
        } else {
          return function() {
            if (p3) {
              return '终止3'
            }
          }
        }
      }
    }
}

function yunxing1() {
    while (test()) {
      test = test()
      if (typeof test === 'string') {
        alert(test)
        return '终止'
      }
    }
}
yunxing1()

let i = 1,
a = 2,

function simpleVlidate() {
    let varr = [];
    varr.push(() => {
      if (i === 1) {
        return '不能等于1'
      }
    })
    varr.push(() => {
      if (a === 2) {
        return '不能等于2'
      }
