错误：语法错误，无法识别的表达式：＃192.168.1.3：8985_solr

var replicasNodeName = "192.168.1.209:8983_solr";
$('"#' + replicasNodeName + '"').append('<a href="#"><span class="badge">5</span></a>');

<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<div class="card">
  <div class="card-body" id="192.168.1.209:8983_solr"> </div>
</div>

Answer 1

另一种方法是，使用本机import os import numpy as np import math import cv2 as cv #path = '/media/D/code/OCR/text-detection-ctpn/data/mlt_english+chinese/image' gt_file = '12.txt' output = open("temp.txt","w") with open(gt_file, 'r') as f: for line in f: line = line.replace("[", "") line = line.replace("(", "") line = line.replace(")", "") line = line.replace("]", "") line = line.replace(" ", "") output.write(line) output.close() os.remove(gt_file) # remove old file os.rename("temp.txt",gt_file) # rename as old file 方法，则无需转义元字符

document.getElementById()

var replicasNodeName = "192.168.1.209:8983_solr";
$(document.getElementById(replicasNodeName)).append('<a href="#"><span class="badge">5</span></a>');

Answer 2

您需要对.和:字符进行转义，因为它们在选择器中具有特殊含义。为此，请在它们之前加上\\。您也不需要字符串中的多余引号。试试这个：

var replicasNodeName = "192\\.168\\.1\\.209\\:8983_solr";
$('#' + replicasNodeName).append('<a href="#"><span class="badge">5</span></a>');

<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<div class="card">
  <div class="card-body" id="192.168.1.209:8983_solr"> </div>
</div>

Answer 3

另一种没有任何转义的解决方案是：

请参见jQuery Selectors以供参考

INamed

var replicasNodeName = "192.168.1.209:8983_solr";
$("*[id='"+ replicasNodeName + "'").append('<a href="#"><span class="badge">5</span></a>');
