我如何从表格中捕获文本区域以外的内容

Question

In a dynamic form, I have the following code to trap 'enter' key.

$(document).bind('keypress', function (e) {  
  if (e.keyCode == 13) { 
    e.preventDefault();
  }
});

Occasionally, there is an element like HTMLTextAreaElement which accept 'enter' key.

how do I unbind preventDefault only for HTMLTextAreaElement.

TIA.

Answer 1

尝试这个：

if (e.which == 13 && e.target.localName !== 'textarea') { 

Answer 2

$("html *:not(textarea)").bind('keypress', function (e) {  
  if (e.keyCode == 13) { 
    e.preventDefault();
  }
});
