[英]Mouseover/MouseOut jquery
I realize how simple this question should be to answer but I am in a medication fog and the answer is escaping me. 我意识到这个问题应该很简单,但是我正处于药雾笼罩中,而答案却在逃避我。
I would like to make this into a simple function to display specific text if the value of the text box is empty upon mouseout and to empty out the text value upon mouseover. 我想使它成为一个简单的函数,以在鼠标移出时如果文本框的值为空而显示特定文本,并在鼠标悬停时移出文本值。
What I have right now that works but is very ugly: 我现在拥有的东西可以工作,但是非常难看:
$(".disappearOnClick").live('mouseover',function() {
if($(this).val() === 'BFA Offset') {
$(this).val('')
}
});
$(".disappearOnClick").live('mouseout',function() {
if($(this).val() === '') {
$(this).val('BFA Offset')
}
});
You can bind to multiple events using the live()
method - so you could use something like this -> 您可以使用
live()
方法绑定到多个事件-这样就可以使用类似的东西->
$('.disappearOnClick').live('mouseover mouseout', function(event) {
if (event.type == 'mouseover') {
if($(this).val() === 'BFA Offset') {
$(this).val('');
}
} else {
if($(this).val() === '') {
$(this).val('BFA Offset');
}
}
});
$(".disappearOnClick").mouseover(function(){...});
and 和
$(".disappearOnClick").mouseout(function(){...});
Would work just as well. 同样会工作。
You should use hover
instead: 您应该改用
hover
:
$(".disappearOnClick").hover(
function(){
//mouseover
},
function(){
//mouseout
}
);
You could try something like this (you could of course change the focus/blur events to mouse-events): 您可以尝试这样的操作(您当然可以将焦点/模糊事件更改为鼠标事件):
http://jsfiddle.net/BD7JA/2/ http://jsfiddle.net/BD7JA/2/
// <input value="BFA Offset" data-placeholder="BFA Offset" class="is-placeholder" />
$('[data-placeholder]').on({
focus: function (evt) {
if ($(this).hasClass('is-placeholder')) {
$(this).val('');
$(this).removeClass('is-placeholder');
}
},
blur: function (evt) {
if ($(this).val() === '') {
$(this).val($(this).data('placeholder'));
$(this).addClass('is-placeholder');
}
}
});
Try this: 尝试这个:
$(".disappearOnClick").mouseenter( function (this) {
if ($('#'+this.id).val() == 'BFA Offset')
$('#'+this.id).val('')
}).mouseleave( function (this) {
if ($('#'+this.id).val() == '')
$('#'+this.id).val('BFA Offset')
});
