我试图使用jQueryUI的自动填充功能来实现网站的快速搜索功能,在我的网站的各种功能的网页。我想你可以说这是像谷歌即时搜索,但它的索引我的网站上的网页。
所以,当他们搜索“创造”,将弹出创建用户选项和创建组织选项。当他们搜索“创建用”它只会显示在创建用户的选择。然后,他们可以点击结果,它会加载该页面。这些都只是一些链接。但正如你所看到的,每个页面都会有一些不同的关键字/同义词那会都指向同一个页面。
确定这样的checkSearchWordsMatchKeywords功能的尽头有一定的工作,因为我已经测试过它。什么是不工作的,我不知道我应该从jQueryUI的搜索返回:函数。
此外,如果你知道如何优化checkSearchWordsMatchKeywords()函数,那么我所有的耳朵。 :)
编辑:下面工作液更新(与jQueryUI的1.9.x的工作):
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 = [];
var numOfLinks = links.length;
// Get entered search terms (request.term) from user and search through all links keywords
for (var k = 0; k < numOfLinks; 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)
{
// When the item is selected, put the label text into the search box
$('#searchTerms').val(ui.item.label);
return false;
},
select: function(event, ui)
{
// Put the selected link's label in the text box and redirect to the url
$('#searchTerms').val(ui.item.label);
// Redirect to the page using .href so the previous page is saved into the user's browser history
window.location.href = ui.item.url;
return false;
}
})
.data('autocomplete')._renderItem = function(ul, item)
{
// Show a description underneath the link label. Using the hyperlink here too so that mouse click still works
return $('<li></li>')
.data('item.autocomplete', item )
.append('<a href="' + item.url + '"><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(searchString, keywords)
{
var searchWords = searchString.toLowerCase().split(' '); // Lowercase the search words & 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;
}

我不“搜索”事件是做你追求的地方。你还是落实source
选项作为回调:
$("#searchTerms").autocomplete({
...
source: function(request, response) {
var matched = [];
// Search "request.term" through all links keywords
for (var k = 0; k < links.length; k++) {
if (checkSearchWordsMatchKeywords(request.term, links[k]['keywords'])) {
matched.push(links[k]);
}
}
// display the filtered results
response(matched);
}
});
request
对象包含term
属性其是在输入输入的文本response
参数是回调,你应该打个电话显示结果。所以基本上,你和筛选数据,并把它传递给response()
显示菜单。
