无法在jQuery中从左到右获取div动画

标签： javascript jquery html css jquery-animate

我有一个列表作为菜单。每次用户点击列表中的某个元素时，我都希望更详细的A从左向右滑动。

因此，如果用户首先点击菜单项A，B会从左向右滑动。如果用户点击A，则B从右向左滑动（从屏幕上消失）并jsfiddle滑入。

我搜索了这个问题并找到了这个post。我合并了 <div class="project"> <ul id="project_menu" class="project_menu"> <li id="menu-php-mysql" data-projectID="php-project">PHP/MySQL</li> <li id="menu-nodejs" data-projectID="node-project">NodeJS</li> <!-- more code --> </ul> <div class="project-detail"> <div id="php-project"> <i class="ion-ios-close-empty close-icon js-close-icon"></i> <div classs="project-text"> <!-- data about project --> </div> </div> <div id="node-project"> <i class="ion-ios-close-empty close-icon js-close-icon"></i> <div classs="project-text"> <!-- data about project --> </div> </div> <!-- and so on.. --> 中的代码，但它没有用。 Chrome调试工具中的js日志中未显示任何错误。单击菜单中的任何项目时没有任何反应。我做错了什么？

#php-project {
    background-color: #9b59b6;
    margin: 30px;
    display: none;
}

$(document).ready(function() {

    itemsToRender = [];

    $('ul#project_menu li').click(function(e) {

        menuItemId = (e.currentTarget.id);

        $('.common').hide();

        $(getProjectId(menuItemId)).css('display', 'inline');

        var value = $(getProjectId(menuItemId)).css('right') === '100px' ? '-100px' : '100px';
        $(getProjectId(menuItemId)).animate({
            right: value                
        }, 800);

    });
});

function getProjectId(menuItemId) {

    if (menuItemId.indexOf('php') > 0) {

        return '#php-project';

    } else if (menuItemId.indexOf('node') > 0) {

        return '#node-project';

    } else if (menuItemId.indexOf('angular') > 0) {

        return '#angular-project';

    } else if (menuItemId.indexOf('mean') > 0) {

        return '#mean-project';

    }          
}

div

Update1 ：@user5325596指出我的详细信息$(getProjectId(menuItemId)).css('display', 'inline-block'); 的显示属性设置为无，因此我通过添加以下内容修复了此问题：

$('.common').hide()

在 Controller file: class ContactsController < ApplicationController def new @contact = Contact.new end def create @contact=Contact.new(params[:contact]) @contact.request=request if @contact.deliver flash.now[:error]=nil else flash.now[:error]='Cannot send message.' render :new end end 之后。

现在，当我点击菜单项时，我可以看到细节div，但它没有动画。

Update2 ：我上传了一个jsFiddle，它包含了我成功使用的jquery动画（fadeIn，已注释掉），以及elchininet建议的代码。

尝试CSS转换，将节省大量代码。也许这不是你想要的，但我相信它会帮助你完成任务。

HTML代码 

<ul>
  <li>One</li>
  <li>Two</li>
  <li>Three</li>
  <li>Four</li>
  <li>Five</li>
</ul>

CSS代码 

li{
  -webkit-transition: all 1s;
  -moz-transition: all 1s;
  transition: all 1s;
}

li.open{
  -webkit-transform: translateX(100px);
  -moz-transform: translateX(100px);
  transform: translateX(100px);
}

jQuery代码 

$("li").on("click", function(){

    $("li.open").removeClass("open");

    $(this).addClass("open");

});

您可以在修改代码jsfiddle并使用div动画。

我在小提琴上发现了一些小错误，比如类名之间的逗号。 ：class="project-container,common"

您使用div class隐藏了所有.common，但之后没有显示。因此即使您向style添加display:none class，其open属性也会获得div。

以下是我更新并正在运行的代码： 

$(document).ready(function() {
   
    itemsToRender = [];
    $('ul#project_menu li').click(function(e) {
       
        
         
        $('.common').hide();
        menuItemId = (e.currentTarget.id);
        var projectId = getProjectId(menuItemId);
        console.log(projectId);
        
        $('.project-container.open').removeClass('open');
        $(projectId).addClass('open');
        $(projectId).show();
        
        
       /* $(projectId).fadeIn('slow'); <--- THIS WORKS! But I want the slide effect instead  */
       });
       
  
  function getProjectId(menuItemId) {
    
    if (menuItemId.indexOf('php') > 0) { 
        return '#php-project';
    
    } else if (menuItemId.indexOf('node') > 0) {
        return '#node-project';
     
    } else if (menuItemId.indexOf('angular') > 0) {
        return '#angular-project';
     
    } else if (menuItemId.indexOf('mean') > 0) {
        return '#mean-project';
     
    }  else if (menuItemId.indexOf('html5-css3-js') > 0) {
        return '#html-css-js-project';

我认为您希望此功能与此fiddle

一样

HTML代码

  <div class="project">
  <ul id="project_menu" class="project_menu">
    <li id="menu-php-mysql" data-projectID="php-project">PHP/MySQL</li>
    <li id="menu-nodejs" data-projectID="node-project">NodeJS</li>
    <!-- more code -->
  </ul>
  <div class="project-detail">
    <div id="php-project">
      <i class="ion-ios-close-empty close-icon js-close-icon"></i>
      <div classs="project-text">
        PHP project text
        <!-- data about project -->
      </div>
    </div>
    <div id="node-project">
      <i class="ion-ios-close-empty close-icon js-close-icon"></i>
      <div classs="project-text">
        Node Project Text
        <!-- data about project -->
      </div>
      <!-- and so on.. -->
    </div>
  </div>
</div>

CSS代码

.project_menu > li{
  cursor: pointer;
}
.project-detail{
  width: 300px;
  height: 100px;
  background-color: #dedede;
  overflow: hidden;
  position: relative;
}

JQuery的

$(document).ready(function() {

  $('.project-detail > div:first-child').css("right","0px");
  itemsToRender = [];
  $('#project_menu li').click(function(e) {
        menuItemId = (e.currentTarget.id);

    $('.common').hide();

    $(getProjectId(menuItemId)).css('display', 'inline');
    var value = '0px';
    $(getProjectId(menuItemId)).animate({
      right: '0px'

    }, 800);
    var req = '.project-detail > div';
    $('.project-detail > div').not($(getProjectId(menuItemId))).animate({
        right: '300px'
    }, 800);

  });
});

function getProjectId(menuItemId) {

  if (menuItemId.indexOf('php') > 0) {
    return '#php-project';

  } else if (menuItemId.indexOf('node') > 0) {
    return '#node-project';

  } else if (menuItemId.indexOf('angular') > 0) {
    return '#angular-project';

  } else if (menuItemId.indexOf('mean') > 0) {
    return '#mean-project';

  }
}
