[英]jquery multiselect doesnt work on dynamically added element into html page
[英]Jquery hover function doesnt run on dynamically added element
这可以成功运作,
$('[rel=notif]').on({
mouseenter: function () {
$(this).find('.solnotifkara').css({"opacity":"0.46"});
},
mouseleave: function () {
$(this).find('.solnotifkara').css({"opacity":"0.36"});
}
});
但是,如果将其动态添加,则无法正常工作。 我有一个click函数,适用于动态添加的元素,
$(document.body).on('click', '[rel="like"]' ,function(){
alert("works");
});
如何使悬停功能适用于动态添加的元素?
$(document).on({
mouseenter: function () {
$(this).find('.solnotifkara').css({opacity:0.46});
},
mouseleave: function () {
$(this).find('.solnotifkara').css({opacity:0.36});
}
}, "[rel=notif]"); // <<<<< delegate here your dynamic element
$(document).on({ mouseenter: function () { $(this).find('.solnotifkara').css({opacity:0.2}); }, mouseleave: function () { $(this).find('.solnotifkara').css({opacity:1}); } }, "[rel=notif]"); // <<<<< delegate here your dynamic element // for test only: $("button").on("click", function(){ $("body").append('<p><a rel="notif">This is a <span class="solnotifkara">note</span>.</a></p>'); });
