如何通过点击关闭我的twitter bootstrap导航栏？

Question

I am trying to get my navbar to auto collapse on click. Specifically when it is on a mobile device. I do not see why the below code will not work but I believe I maybe have the '.nav navbar-toggle a' wrong.

HTML

<div class="navbar navbar-fixed-top navbar-default" role="navigation">
  <div class="container">
    <div class="navbar-header">
      <button type="button" class="navbar-toggle" data-toggle="collapse" data-target=".navbar-collapse">
        <span class="sr-only">Toggle navigation</span>
        <span class="icon-bar"></span>
        <span class="icon-bar"></span>
        <span class="icon-bar"></span>
      </button>
         <a class="navbar-brand" href="#"></a>
    </div>
    <div class="collapse navbar-collapse" id="close">
      <ul class="nav navbar-nav">
        <li class="navtext"><a href="#about">ABOUT</a></li>
        <li class="navtext"><a href="#services">SERVICES</a></li>
        <li class="navtext"><a href="#work">WORK</a></li>
        <li class="navtext"><a href="#contact">CONTACT</a></li>
      </ul>
    </div><!--/.nav-collapse -->
  </div>
</div>

Java script (I added this code to the end of bootstrap.js)

function close_toggle() {
if ($(window).width() <= 768) {
  $('.nav.navbar-nav a').on('click', function(){
      $("#close").click();
  });
}
else {
 $('.nav.navbar-nav a').off('click');
}
}
close_toggle();

$(window).resize(close_toggle);

Thank to Hide Twitter Bootstrap navbar on click

Answer 1

I commented first:

('.nav navbar-nav a') should be ('.nav.navbar-nav a') see: CSS rule to apply only if element has BOTH classes and you should apply your click for closing on .navbar-collapse if i understand your question well

When i test the above i think i should work with the code shown below.

<script>
function close_toggle() {
if ($(window).width() <= 768) {
  $('.nav.navbar-nav a').on('click', function(){
      $('.navbar-collapse').collapse('hide');
  });
}
else {
 $('.nav.navbar-nav a').off('click');
}
}
close_toggle();

$(window).resize(close_toggle); 
</script>

NB i think .collapse('hide'); make more sense (more readable) than doing click although the effect will be the same maybe.

Its already doing it. Make sure you added the viewport in your metatags

<meta name="viewport" content="initial-scale=1">
