两个input可能会用到的小方法

1.一个普通的input元素，在不被 form包裹的时候，如何跳转或搜索

var oInput = document.getElementsByTagName('input')[0];
    oInput.addEventListener('keyup',function(event){
      var event = event || window.event;
      if(event.keyCode === 13) {
        location.href = 'http://www.baidu.com/s?wd=' + this.value;
      }
    })

2.多个input按enter输入下一项

document.addEventListener('DOMContentLoaded', function () {
        var oInputs = document.getElementsByTagName('input');
        var len = oInputs.length;
        for (var i = 0; i < len; i++) {
          console.log(i);
          (function (i) {
            oInputs[i].addEventListener('keydown', function (event) {
              event = event || window.event;
              console.log(event.keyCode);
              if (this.type != 'submit' && event.keyCode === 13) {
                event.preventDefault();
                oInputs[i + 1].focus();
              }
            })
          })(i)
        }
      })
