Question

基本上我似乎可以在wordpress中运行jquery。在这里，我已经设置了一个测试页面来演示 - https://www.painandinjurysolutions.co.uk/155-2/。

我正在使用教程代码 - http://codepen.io/Guilh/pen/JLKbn

＆＃13;

var  mn = $(".main-nav");
    mns = "main-nav-scrolled";
    hdr = $('header').height();

$(window).scroll(function() {
  if( $(this).scrollTop() > hdr ) {
    mn.addClass(mns);
  } else {
    mn.removeClass(mns);
  }
});

＆＃13;

* {
  box-sizing: border-box;
}
body {
  margin: 0;
  padding-top: 250px;
}
header {
  height: 300px;
  padding-top: 50px;
  background: #f07057;
}
.main-nav,
.main {
  position: relative; 
}
.main-nav {
  background: #fff;
  height: 80px;
  z-index: 150;
  margin-bottom: -80px;
  box-shadow: 0 2px 3px rgba(0,0,0,.4);
}
header,
.main-nav-scrolled {
  position: fixed;
  width: 100%;
  top: 0;
}
.main {
  background: #f2f2e8;
  padding: 110px 50px 50px;
  column-count: 2;
  column-gap: 40px;
}

这与show完全相同，但我已经替换了所有jquery选择器＆＃34; $＆＃34;用＆＃34; jQuery＆＃34;。

脚本在事件列表中加载＆＃39;滚动＆gt;窗口＆＃39;它应该是这样，但页面滚动时没有任何视觉效果（当您向下滚动时，导航栏应该粘在页面顶部）。我有一种感觉，我没有正确地将它排队或者某种东西或者可能称为正确的依赖关系，但我不明白为什么它在页面中加载但什么都不做。

我的相关函数代码段是：

function verdigris_script() {
// register your script location, dependencies and version
    wp_register_script('custom_js', get_template_directory_uri() . '/js/scripts.js', array('jquery'));
    //css
    //wp_enqueue_style('bootstrap', get_template_directory_uri() . '/css/bootstrap.min.css', array(), 'all');
    wp_enqueue_style('customstyle', get_template_directory_uri() . '/css/verdigris-style.css', array(), 'all');
    //js
    //wp_enqueue_script('bootstrapjs', get_template_directory_uri() . '/js/bootstrap.min.js', array(), true);
    wp_enqueue_script('custom_js');

}
add_action( 'wp_enqueue_scripts', 'verdigris_script');

Answer 1

用

替换你的脚本

$(function($) {
var  mn = $(".main-nav");
    mns = "main-nav-scrolled";
    hdr = $('header').height();

$(window).scroll(function() {
  if( $(this).scrollTop() > hdr ) {
    mn.addClass(mns);
  } else {
    mn.removeClass(mns);
  }
});
})(jQuery)

Answer 2

您需要在jQuery代码中使用document.ready函数。

$(document).ready(function(){

   // jQuery goes here...

});

或简称：

$(function(){

   // jQuery goes here...

});

此外，如果您需要测试jQuery是否正常工作，只需在document.ready函数中尝试console.log('hey is this working');。

希望这有帮助

jQuery似乎没有在wordpress网站上运行
