Unselect what was selected in an input with .select()

问题

After I use .select() to select the text in the input box when hovered over I did the following:

HTML:

<input type="text" class="hoverAble" value="hover here"/><br />

jQuery:

$(".hoverAble").mouseenter(function() {

    this.select();

}).mouseleave(function() {

    //I can't figure what to put here.
});

See here. ^{Warning for it to function correctly (in jsfiddle) you must click once in the result frame.}

The main idea is mouseleave is working as as expected also.

As you might have noticed, I can't figure out a way to un-select the text when you hover out and avoid this:

回答1:

use .blur();

回答2:

If you are using jQuery, try using blur().

$(this).blur();

In this case, blur() only unfocus from the input text, and although it gives the appearance the text is not selected anymore, it is still selected. To truly unselect any text, you would do:

$(".hoverAble").mouseenter(function() {
    this.select();
}).mouseleave(function() {
    $(this).prop('selectionStart', 0).prop('selectionEnd',0).blur();
});

This works:

$(".hoverAble").hover(function() {

    $(this).select();
    $(this).after("<input type='text' style='height:0;width:0;border:0;padding:0;margin:0;' id='tmp_hidden' />");

}, function(){

    $("#tmp_hidden").select().remove();

});

There should be a better way to solve it thought.

Edit: of course there's blur().

input.hover(function(){$(this).select();}, function(){$(this).val($(this).val());});

回答6:

if you use jQuery, you could try one of the many plugins for unselecting or setting the caret position by your needs, e.g. this one. if you don't, you still can use the pure JavaScript of these plugins due to the open-source-licences
