Demo1： Local数据：

<span style="font-family:Courier New;">var substringMatcher = function(strs) {
return function findMatches(q, cb) {
var matches, substringRegex;

// an array that will be populated with substring matches
matches = [];

// regex used to determine if a string contains the substring `q`
substrRegex = new RegExp(q, 'i');

// iterate through the pool of strings and for any string that
// contains the substring `q`, add it to the `matches` array
jQuery.each(strs, function(i, str) {
if (substrRegex.test(str)) {
matches.push(str);
}
});

cb(matches);
};
};</span>
