Answer 1

创建一个元素并设置其文本，然后您不必对其进行编码：

var post = $('<div/>', { 'class': 'postbody' });
post.text("this is tom's and bill's post");
$('#post-content').append(post);​

Answer 2

你可以使用

var postbody = '<div class="postbody">this is tom\'s and bill\'s post</div>';

或者

var postbody = "<div class=\"postbody\">this is tom's and bill's post</div>";

Answer 3

如果您真的想替换字符串中的某些内容，只需使用 replace()：

var postbody = "<div class=\"postbody\">this is tom's and bill's post</div>";
postbody = postbody.replace(/\'/g, "&#39;");

Answer 4

尝试使用这个

var postbody = "<div class='postbody'>this is tom's and bill's post</div>";
var postid = $('#post-content');
postid.append(postbody);​
