[英]Why justifying with execCommand does not work properly?
為什么用execCommand進行對齊無法正常工作? 檢查以下代碼:
$('#JustifyLeft').click(function(){ document.execCommand("JustifyLeft", false, ""); });
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script> <p>Select whole text and click the button</p> <div class="editable" contenteditable="TRUE" style="font-size: 27px; text-align: center;"> <span style="font-weight: bold; font-style: italic; text-decoration: underline;">Hi<span style="font-size: 35px;">I</span>am<span style="font-size: 18px;">Blah Blah</span>Ok</span> </div> <input type="button" id="JustifyLeft" value="Align Left">
在選擇了整個文本並將其對齊后,您將看到下划線僅保留在<text>
節點上,而<span>
節點沒有文本修飾。
這是錯誤嗎? 有沒有辦法糾正它?
如果您在開發人員工具中查看元素結構,您將看到execCommand在Hi,am和Ok之后添加了</span>
,並用<div>
包裹起來,如下所示
<div style="text-align: left;">
<span style="font-style: italic; font-weight: bold; text-decoration: underline;">Hi</span>
<span style="font-style: italic; font-weight: bold; font-size: 35px;">I</span>
<span style="font-style: italic; font-weight: bold; text-decoration: underline;">am</span>
<span style="font-style: italic; font-weight: bold; font-size: 18px;">Blah Blah</span>
<span style="font-style: italic; font-weight: bold; text-decoration: underline;">Ok</span>
</div>
您可以通過將第一個<span>
更改為<div>
來糾正它,如下所示
<div style="font-weight: bold; font-style: italic; text-decoration: underline;">Hi
<span style="font-size: 35px;">I</span>am
<span style="font-size: 18px;">Blah Blah</span>Ok
</div>
