Jquery自动完成验证程序

Question

我已经添加了一个搜索下拉菜单与jQuery。它工作正常，当我输入不匹配的数据时，显示not match消息。但是，当我选择其中一个下拉项目，然后通过删除某些字符进行更新时，not match不会显示。怎么可能做到这一点？

var aTags = ["ask", "always", "all", "alright", "one", "foo", "blackberry", "tweet", "force9", "westerners", "sport"]; 

var bTags = ["aaaaaaa", "bbbbbbbb", "ccccccc", "ddddddddd"]; 


$("#tags").autocomplete({ 
    source: aTags.concat(bTags), 
    response: function(e, result) { 
    if (!result.content.length) { 
     console.log('No matches!'); 
     jQuery('#messag').html("Not match...").show(); 
    } else { 
     jQuery('#messag').hide(); 
    } 
    } 
});

您的代码工作正常，如果您从列表中匹配一些单词，然后删除最后一个字符它仍将匹配词，因为是和自动完成......，只要它包含了一些潜台词它将被匹配..

var aTags = ["ask", "always", "all", "alright", "one", "foo", "blackberry", "tweet", "force9", "westerners", "sport"]; 
 

 
var bTags = ["aaaaaaa", "bbbbbbbb", "ccccccc", "ddddddddd"]; 
 

 

 
$("#tags").autocomplete({ 
 
    source: aTags.concat(bTags), 
 
    response: function(e, result) { 
 
    console.log(result); 
 
    if (!result.content.length) { 
 
     console.log('No matches!'); 
 
     jQuery('#messag').html("Not match...").show(); 
 
    } else { 
 
     jQuery('#messag').hide(); 
 
    } 
 
    } 
 
});
