Answer 1

您的代码几乎是正确的，问题在于正则表达式的语法。您不需要将其放在引号中，$字符需要转义，因为它在Regex中具有特殊含义。

另请注意，您可以为html()提供修改值的功能，而不是多次选择元素。也可能值得使用text()，因为您似乎在p元素的内容中没有任何HTML。试试这个：

＆＃13;

$(".replace").on("click", function(e) {
  $(".str_content").html(function(i, html) {
   return html.replace(/355#00\$1/g, '7777777');
  });
});

使用replace like，

var new_data=data.replace(/355#00\$1/ig,'7777777');

$(".replace").on("click",function(e){
    var data=$(".str_content").html();  
    var new_data=data.replace(/355#00\$1/ig,'7777777');
    $(".str_content").html(new_data);
});

<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.9.1/jquery.min.js"></script>
<p class="str_content">
