jQuery blur event with ID and value

问题

I want to use the 'blur' event in the jQuery text plugin. http://jqueryte.com

$ ('textarea'). jqte ({
blur: function (elem) {
// ID textarea?
// Content editor?
}
});

The function of the blur, I would like to determine the content and the ID of the textarea.

Can you help me with an idea?

回答1:

Since it doesn't look like the blur event is passing any arguments to the callback you might have to do something like

$("textarea").each(function(idx, elem) {
  $(this).jqte({
    blur: function() {
      console.log('blur', this, arguments);
      console.log(elem.id);
      $('#log').append('<div>' + elem.id + '</div>')
    }
  });
})

<div id="log"></div>
<textarea id="t1"></textarea>
<br />
<textarea id="t2"></textarea>
<br />
<textarea id="t3"></textarea>
<br />
