JavaScript 通过劫持Enter键防止提前表单提交

Posted 2021-05-20

var inputs = $$('input.hijack'); 

$each(inputs,function(el,i) { 

  el.addEvent('keypress',function(e) { 

    if(e.key == 'enter') { 

      e.stop(); 

      if(inputs[i+1]) { inputs[i+1].focus(); } 

      //last one? 

      if(i == inputs.length-1) { $('submit-button').focus(); } 

    } 

  }); 
});
