标签: html css button properties click

我有4个简单的按钮。我怎么能设置它们,所以当点击其中一个时它有一些属性改变并保持变化?当另外一个按钮被点击时,它会改变相同但它会将第一个按钮的属性恢复为“正常”?基本上,它们是导航按钮,我希望它们显示您所在的页面的哪个部分。提前谢谢。

我为点击制作了一个示例并仅更改了背景颜色:

<强> CSS

.beforeClick {
    background-color:#EEE;
}

<强>的JavaScript

$(document).ready(function (){
   $('.beforeClick').click(function (){
       $('.beforeClick').css('background-color',"#EEE");
           $(this).css('background-color',"#555");
   });
});

<强> HTML

<button class="beforeClick">btn1</button>
<button class="beforeClick">btn2</button>
<button class="beforeClick">btn3</button>
<button class="beforeClick">btn4</button>
<button class="beforeClick">btn5</button>

(你需要jQuery)

利用课程来切换按钮的状态。类似的东西:

<div class="button">PRESS</div>
....
<div class="button">PRESS</div>

只需要另一个.selected类,你可以通过几行vanilla JavaScript来覆盖你的场景:

var buttons = document.getElementsByClassName('button');

for (var i = 0; i < buttons.length; i++) { //loop through all buttons
    buttons[i].addEventListener('click', function() {
        if (document.getElementsByClassName('selected').length) { //check if we already have a selected element
            document.getElementsByClassName('selected')[0].className = document.getElementsByClassName('selected')[0].className.replace(/(?:^|\s)selected(?!\S)/g, ''); //remove selected class from "old" element
        }
        this.className += ' selected'; //add selected class to element that has been clicked / called the handler
    });
}​

我要做的是编写一个javascript函数,例如:

     <script type='text/javascript'>
     function toggle(btn)
     {
          var btnArray = document.getElementsByClassName('button');
          for(i = 0; i < btnArray.length; i++)
          {
              if(btn == btnArray[i])
              {
                  //the button is the button which is clicked
                  if(!btn.classList.contains("clicked"))
                  {
                      btn.className += " clicked";
                  }
              }
              else
              {
                  //remove class clicked, just reset the classname
                  btnArray[i].className = "button";
              }
          }


     }

     </script>

     <button class="button" onclick="toggle(this);">btn1</button>
     <button class="button" onclick="toggle(this);">btn2</button>
     <button class="button" onclick="toggle(this);">btn3</button>

您可以在css中添加“clicked”类的说明。

    .clicked{
        background-color: red;
    }

(我在Chromium中测试了这段代码,但它确实有效。)
