Question

使用JQuery，我希望能够通过单击页面上的其他位置（任何不是汉堡）来折叠我的导航。我想我理解逻辑，但却无法使其发挥作用。

请参阅以下JFiddle。 https://jsfiddle.net/ywkxyjx3/33/

这是我到目前为止的逻辑：

$(".burger").click(function() {
  $(".nav").toggleClass("show", 900); // toggles on .show css
  $(".burger").toggleClass("change"); // toggles on .change css for hamburger animation
});

$('body').click(function(event){ //onBodyclick
  if ($(!event.target).closest('.navCont').length) { //if click isnt 
navCont or any child elements then..
    return; //do nothing
  } else {
    // do something when not targeted
  }
});

经过一些研究后，我发现了类似的问题，但我没有将它应用到我自己的自建导航中。

Answer 1

查看以下代码。

＆＃13;

$(".burger").click(function() {
  $(".nav").toggleClass("show", 900);
  $(".burger").toggleClass("change");
});

$('body').click(function(event){
  if ($(!event.target).closest('.navCont').length) {
    return; //do nothing
  } else {
  	// do something when not targeted
  }
});

$('html').click(function() {
   $(".nav").removeClass("show", 900);
   $(".burger").removeClass("change");
});

$('#navCont').click(function(event){
     event.stopPropagation();
});

＆＃13;

#navCont {
  width: 47px;
  height: auto;
  float: right;
}


/*Dropdown Nav*/

.nav {
  position: absolute;
  display: block;
  height: 0px;
  float: right;
  overflow: hidden;
  top: 55px;
  opacity: 99;
  text-align: center;
  box-shadow: 0px 8px 16px 0px rgba(0, 0, 0, 0.2);
}

.nav a {
  color: black;
  text-decoration: none;
}

.show {
  height: auto;
}

.burger {
  /* box around hamburger. Has onclick function*/
  display: inline-block;
  position: relative;
  float: right;
  padding: 5px;
  cursor: pointer;
}


/*Individual lines of burger*/

.bar1,
.bar2,
.bar3 {
  width: 36px;
  height: 4px;
  border-radius: 2px;
  background-color: #95449a;
  margin: 6px 0;
  /*seperate the lines*/
  transition: 1s;
  /*time taken for any animation to take place */
}


/*in html classlist.toggle(change)*/

.change .bar1 {
  -webkit-transform: translateY(10px) rotate(45deg);
  transform: translateY(10px) rotate(45deg);
}

.change .bar2 {
  opacity: 0;
  -webkit-transform: translateX(10px);
  transform: translateX(10px);
}

.change .bar3 {
  -webkit-transform: translateY(-10px) rotate(-45deg);
  transform: translateY(-10px) rotate(-45deg);
}

＆＃13;

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>

  <div class="burger">
    <div class="bar1"></div>

  </div>
</div>

试试这个：

order by DATE(SUBSTRING_INDEX(SUBSTRING_INDEX(field_name,'json_field_key1":"',-1),'"',1)) DESC

$(".burger").click(function(event) {
  $(".nav").toggleClass("show", 900);
  $(".burger").toggleClass("change");
  event.stopPropagation();
});
$(document).click(function(event) { 
   if($('.change').length){
      $(".nav").toggleClass("show", 900);
      $(".burger").toggleClass("change");
  }
});

#navCont {
  width: 47px;
  height: auto;
  float: right;
}


/*Dropdown Nav*/

.nav {
  position: absolute;
  display: block;
  height: 0px;
  float: right;
  overflow: hidden;
  top: 55px;
  opacity: 99;
  text-align: center;
  box-shadow: 0px 8px 16px 0px rgba(0, 0, 0, 0.2);
}

.nav a {
  color: black;
  text-decoration: none;
}

.show {
  height: auto;
}

.burger {
  /* box around hamburger. Has onclick function*/
  display: inline-block;
  position: relative;
  float: right;
  padding: 5px;
  cursor: pointer;
}


/*Individual lines of burger*/

.bar1,
.bar2,
.bar3 {
  width: 36px;
  height: 4px;
  border-radius: 2px;
  background-color: #95449a;
  margin: 6px 0;
  /*seperate the lines*/
  transition: 1s;
  /*time taken for any animation to take place */
}


/*in html classlist.toggle(change)*/

.change .bar1 {
  -webkit-transform: translateY(10px) rotate(45deg);
  transform: translateY(10px) rotate(45deg);
}

.change .bar2 {
  opacity: 0;
  -webkit-transform: translateX(10px);
  transform: translateX(10px);
}

.change .bar3 {
  -webkit-transform: translateY(-10px) rotate(-45deg);
  transform: translateY(-10px) rotate(-45deg);
}

Answer 3

这是我的想法。

$(".burger").click(function(event) {

   // Added this to make sure $('body').click doesn't override open nav function
   event.stopPropagation() 

   $(".nav").toggleClass("show", 900);
   $(".burger").toggleClass("change");
});

// then when you click the body, it checks to see whether or not it is already open, if it is, close it.

$('body').click(function(){
  if ($(".nav").hasClass('show') && $(".burger").hasClass('change') ) {
    $(".nav").toggleClass("show", 900);
    $(".burger").toggleClass("change");
  } 
})
