json文件test.json内容如下：

[{"id":"11","companyname":"公司测试五"},{"id":"10","companyname":"json生成测试"},{"id":"9","companyname":"json不转义测试"},{"id":"8","companyname":"测试公司"},{"id":"7","companyname":"测试公司"},{"id":"6","companyname":"公司测试四"},{"id":"5","companyname":"测试公司"},{"id":"3","companyname":"测试公司二"},{"id":"2","companyname":"测试公司一"},{"id":"1","companyname":"公司测试"}]

js代码：

$.getJSON('json/test.json', function(json){
var getlist = json.filter(
	(item)=>item.companyname.includes(qstring)//qstring为需要搜索的关键字
);
if (getlist.length > 0) {
	var strlist = '<ul id="customerlistSelector">';
	for (var i=0; i<getlist.length; i++) {
		strlist += '<li>'+getlist[i].companyname+'</li>';
	}
	strlist += '</ul>'

	iDiv.innerHTML = strlist;
}
