我在表格中有地址栏。我将表单转换为json后发送到Web服务器。出乎意料的是，当用户在地址字段中输入文本'X' Road时，正在使用\进行转义。我将该信息保存在数据库中，然后发送回客户端。jresp = '{% autoescape on%}{{jresp}}{% endautoescape %}';
但不幸的是，此处未显示转义字符。遇到文本'X Road'时，标签关闭
这是代码段...
jresp =

它不应该引发错误，但是控制台中出现错误！
问题：
该如何解决？
到底是什么引起了该问题？
最佳答案
autoescape标记转义特殊的HTML字符（<和>），而不是单引号。
如果要转义单引号，可以编写custom template filter。
例如：
from django import template
register = template.Library()
@register.filter
def escape_single_quotes(string):
# The two backslashes are interpreted as a single one
# because the backslash is the escaping character.
return string.replace("'", "\\'")
如果您不希望使用模板过滤器，则可以执行以下操作：
{# Note the type is not "text/javascript" so the browser does not try to interpret the content. #}
<script id="jresp" type="application/json">{{ jresp }}</script>
<script>
var jsresp = document.getElementById('jsreps').innerHTML;
</script>
第二种解决方案是更好的做法，因为您没有使用Django渲染JS，这意味着可以将其移动到外部文件中。
