Extjs 商店过滤 - 包括元字符
我有一个具有注释字段（文本区域）的数据存储，并且想要显示满足用户输入（甚至是元字符）的所有注释。
我编写了以下函数来处理此问题：
function notefilter() {
var newfilter = Ext.getCmp('searchnote');
var searchStr = newfilter.getValue();
searchStr = searchStr.replace('?', '\\?').replace('*', '\\*').replace('+', '\\+').replace('{', '\\{').replace('}', '\\}').replace('[', '\\[').replace(']', '\\]').replace('(', '\\(').replace(')', '\\)').replace('|', '\\|').replace('$', '\\$').replace('^', '\\^');
var re = new RegExp(".*" + searchStr + ".*", "ig");
Ext.getCmp('notesgrid').store.filter('Note', re);
}
但是，即使在转义元字符之后，过滤器也无法搜索元字符，但它适用于所有其他字母数字输入。
我错过了什么吗？
提前致谢 ！
I have a data store having a Note field (a textarea) and want to display all Notes satisfying a user input (even metacharacters).
I've written the following function to handle this:
function notefilter() {
var newfilter = Ext.getCmp('searchnote');
var searchStr = newfilter.getValue();
searchStr = searchStr.replace('?', '\\?').replace('*', '\\*').replace('+', '\\+').replace('{', '\\{').replace('}', '\\}').replace('[', '\\[').replace(']', '\\]').replace('(', '\\(').replace(')', '\\)').replace('|', '\\|').replace('
However the filter fails to search for metacharacters even after escaping them, but it works are all other alphanumeric input.
Am I missing something ?
Thanks in advance !

最后，让过滤器开始工作。 JavaScript 内置
escape()&encodeURIComponent()为我完成了这项工作。我不必以编程方式转义元字符。Finally, got the filter working. JavaScript's built in
escape()&encodeURIComponent()did the work for me. I do not have to programatically escape the metachars.
