[英]text+variable concatenation as string inside appendChild($variable) with pure javascript
我知道JavaScript为零。 我通过转换和组合小脚本达到了我的大部分要求。 但是,在我下面描述的那一点上,我无法完全解决我的要求。
我也想在我的常量文本之前打印超链接id的值。 我不使用jQuery。
例如,暂时只写“ 正在被答复 ”。
但是(假设超链接id = 6)它应该写为“ 6 正在被暂时答复。 ”
我已经阅读过此类问答,但我无法从中受益。 ( JS:如何在appendChild()中连接变量? )
身体标签中的JS
function reply_comment (id) {
var LinkId = document.getElementById('parent_id');
LinkId.value = id;
var message = document.createTextNode(" is being replied by the time being.");
document.getElementById('print_id').appendChild(message);
document.getElementById("focus_id").focus();
}
HTML
<!-- codes given above -->
<script type="text/javascript">
... ... ...
</script>
<!-- codes given above -->
<!-- when clicked on the hyperlink, store the hyperlink id value (id value is an unsigned integer) -->
<!-- print the stored id from hyperlink into the value="{unsigned integer id}" part of input ( type:text and id="parent_id" )-->
<!-- focus on comment form's input ( type:text and id="focus_id" ) -->
<!-- print preset message between span tags ( span tag id="print_id" ) -->
<a class="rep" href="#focus_id" onclick="reply_comment(this.id);" id="6" rel="nofollow">reply comment</a>
<p>filling words</p><p>filling words</p><p>filling words</p><p>filling words</p><p>filling words</p><p>filling words</p><p>filling words</p><p>filling words</p><p>filling words</p><p>filling words</p><p>filling words</p><p>filling words</p><p>filling words</p><p>filling words</p><p>filling words</p><p>filling words</p><p>filling words</p><p>filling words</p><p>filling words</p><p>filling words</p><p>filling words</p><p>filling words</p><p>filling words</p><p>filling words</p><p>filling words</p><p>filling words</p><p>filling words</p><p>filling words</p>
<span id="print_id"></span>
<form>
<label for="focus_id">Focus the cursor below</label>
<input type="text" id="focus_id" name="focus_id">
<label for="parent_id">Paste parent_id below</label>
<input type="text" id="parent_id" name="parent_id" value="">
</form>
对我来说,您似乎从未将LinkId.value = id
添加到您的message
:
function reply_comment (id) {
var LinkId = document.getElementById('parent_id');
LinkId.value = id;
var message = document.createTextNode(id + " is being replied by the time being.");
document.getElementById('print_id').appendChild(message);
document.getElementById("focus_id").focus();
}

我所做的只是在" is being replied by the time being."
添加id +
" is being replied by the time being."
为了连接,只需使用+
运算符。 您可以合并很多东西。 示例: var string = "MY " + "CONCATENATED " + " STRING";
将输出"MY CONCATENATED STRING"
。 等等。
