我正在尝试使用jQueryUI自动完成功能为我网站中的各种功能页面实现网站快速搜索功能。因此,当他们搜索“创建”时,将显示“创建用户”选项和“创建组织”选项。当他们搜索“创建你”时,它只会显示“创建用户”选项。这些只是一些链接。但正如您所看到的,每个页面都会有一些不同的关键字/同义词,它们都指向同一页面。
基本上我想要一个像这样的结构:
var links = [
{
keywords: ['create', 'add', 'make', 'insert', 'user'],
label: "Create user",
desc: "Create a user in the system",
url: 'http://mysite.com/user/create/'
},
{
keywords: ['create', 'add', 'make', 'insert', 'organisation'],
label: "Create organisation",
desc: "Create an organisation in the system",
url: 'http://mysite.com/organisation/create/'
}];
因此,当他们输入时,它应该查找链接数组,然后搜索关键字数组,根据他们输入的内容搜索部分文本匹配。如果找到一个,那么它将在自动中显示该条目完成者。但是,如果第二个或第三个搜索词与任何关键词都不匹配,那么它就不会显示它。
现在我听说你可以通过提供源作为回调来做到这一点吗?
到目前为止,这是我的代码(编辑:使用工作解决方案更新):
var links = [
{
keywords: ['create', 'add', 'make', 'insert', 'user'],
label: "Create user",
desc: "Create a user in the system",
url: 'http://mysite.com/user/create/'
},
{
keywords: ['create', 'add', 'make', 'insert', 'organisation'],
label: "Create organisation",
desc: "Create an organisation in the system",
url: 'http://mysite.com/organisation/create/'
}];
$("#searchTerms").autocomplete(
{
minLength: 2,
source: function(request, response)
{
var matched = [];
// Get entered search terms (request.term) from user and search through all links keywords
for (var k = 0; k < links.length; k++)
{
// If it matches, push the object into a new array
if (checkSearchWordsMatchKeywords(request.term, links[k]['keywords']))
{
matched.push(links[k]);
}
}
// Display the filtered results
response(matched);
},
focus: function( event, ui )
{
$( "#searchTerms" ).val( ui.item.label );
return false;
},
select: function( event, ui )
{
// Redirect to the url
$( "#searchTerms" ).val( ui.item.label );
window.location.replace(ui.item.url);
return false;
}
})
.data( "autocomplete" )._renderItem = function( ul, item ) {
return $( "<li></li>" )
.data( "item.autocomplete", item )
.append( '<a href=""><b>' + item.label + '</b><br>' + item.desc + '</a>' )
.appendTo( ul );
};
/**
* Check that each word in a search string matches at least one keyword in an array
* E.g. searchWords = 'create use' and keywords = ['create', 'add', 'make', 'insert', 'user'] will return true
*/
function checkSearchWordsMatchKeywords(searchWords, keywords)
{
var searchWords = searchWords.toLowerCase(); // Lowercase the search words
var searchWords = searchWords.split(' '); // Break up the search into separate words
var numOfSearchWords = searchWords.length; // Count number of search words
var numOfKeywords = keywords.length; // Count the number of keywords
var matches = []; // Will contain the keywords that matched the search words
// For each search word look up the keywords array to see if the search word partially matches the keyword
for (var i = 0; i < numOfSearchWords; i++)
{
// For each keyword
for (var j = 0; j < numOfKeywords; j++)
{
// Check search word is part of a keyword
if (keywords[j].indexOf(searchWords[i]) != -1)
{
// Found match, store match, then look for next search word
matches.push(keywords[j]);
break;
}
}
}
// Count the number of matches, and if it equals the number of search words then the search words match the keywords
if (matches.length == numOfSearchWords)
{
return true;
}
return false;
}
});
好的,所以checkSearchWordsMatchKeywords函数最后肯定有效,因为我已经测试过了。什么是行不通的是我不知道我应该从jQueryUI搜索中返回什么:function。
请帮忙吗?

我在工作中遇到了这个问题。为了解决这个问题,我们创建了自己的搜索功能。即使它们在您想要显示的实际字符串中,也要搜索keywords
。
$( "#searchTerms" ).autocomplete({
search: function(event, ui) {
// Add your super search function here
}
});
