表格中带文本框，只能输入数值

numberChange(val, index) {
      let integer = /^(-|\+)?\d+$/;
      if (integer.test(val)) {
        if (this.tableData[index].thirdScore == 0) {
          this.tableData[index].getDetailScore = parseInt(val);
        } else {
          this.tableData[index].getDetailScore = parseInt(val);
          this.$nextTick(() => {
            let newVal = Math.min(
              parseInt(val),
              this.tableData[index].thirdScore
            );
            this.tableData[index].getDetailScore = newVal;
          });
        }
      }
}
