使用Java脚本删除HTML中的背景色和字体颜色 [英] Remove background color and font color in HTML with Javascript

问题描述

我正在改进TinyMCE编辑器，并希望在原色和背景色中添加按钮默认颜色.这是我如何获得具有随机背景颜色样式的选定文本的方法:

I am improving TinyMCE editor and want to add buttons Default color in forecolor and backcolor. This is how I get selected text with random style of background colors:

outer = tinyMCE.activeEditor.selection.getNode().outerHTML;

例如，可能会有类似的内容:

For example, there could be something like this:

<p style="font-size: 18px;"> 
    sadasdasdsasdasda
    <span style="background-color: rgb(0, 255, 0);" data-mce-style="background-color: #00ff00;">sdasdasda</span>
    <span style="background-color: rgb(255, 0, 0);" data-mce-style="background-color: #ff0000;">
        <span style="background-color: rgb(0, 255, 0);">sdasd</span>
        asdasdasdas
    </span>
    dasdasd
</p> 

我已经在jQuery中尝试过.each，但是没有用.这是实际的代码:

I already tried .each in jQuery, but not worked. This is that actual code:

$(outer).each(function() {
    $(this).css({'background-color': 'transparent'});
});

我不是Java的高手，也不是jQuery的高手.我该怎么做才能从outer中删除所有background-color?

I am not master in Javascript, neither in jQuery. What could I do to remove all background-color from outer?

推荐答案

所需要的只是插件(plugins/textcolor/plugin.js)中的编辑功能.那么结果将是:

All to need is edit function in plugin (plugins/textcolor/plugin.js). Then result will be:

function onPanelClick(e) {
   var buttonCtrl = this.parent(), value;

   if ((value = e.target.getAttribute('data-mce-color'))) {
      buttonCtrl.hidePanel();
      buttonCtrl.color(value););
      if (value == 'transparent') {
         tinyMCE.execCommand("RemoveFormat");
      } else {
         editor.execCommand(buttonCtrl.settings.selectcmd, false, value);
      }
   }
}

在那之后，还需要编辑tinymce.js.所有需要的是编辑器removeformat，例如:

After that, edit tinymce.js is required too. All to need is editor removeformat, for example:

removeformat: [
   {selector: 'span', styles: ['background-color'], remove: 'empty', split: true, expand: false, deep: true}
]

(供其他用户使用)向面板添加新颜色，将此代码插入函数renderColorPicker()中，建议在循环之前使用

(FOR OTHER USERS) to add new color to panel, insert this code in function renderColorPicker(), recommended before loop:

function renderColorPicker() {
   ...

   html += '<tr>';
   html += (
      '<td colspan="' + cols + '">' +
         '<div id="' + ctrl._id + '-00" class="color-box"' +
         ' data-mce-color="transparent"' +
         ' role="option"' +
         ' tabIndex="-1"' +
         ' style="background-color: transparent"' +
         ' title="Default color">' +
         '<span>Default color</span></div>' +
      '</td>'
   );
   html += '</tr>';

   for (y = 0; y < rows; y++){
   ...
