select2的用法

$("#liaison").select2({
ajax: {
url: "../../weixin/ashx/outside/applicat.ashx?action=liaison",
dataType: 'json',
delay: 250,
data: function (params) {
return {
q: params.term, // 输入的值
page: params.page
};
},
processResults: function (data, params) {

params.page = params.page || 1;

return {
results: data.items, //返回值格式[{id:1,text:'text'},{id:2,text:'text'}]如果不按照此格式数据可能显示不出来，或者再次选择时值赋不上。
pagination: {
more: (params.page * 10) < data.total_count
}
};
},
cache: true
},
placeholder: '联络人搜索',
escapeMarkup: function (markup) { return markup; }, //自定义显示
minimumInputLength: 2, //输入长度
templateResult: formatRepo,
language: "zh-CN",
templateSelection: formatRepoSelection
});

function formatRepo(repo) {
if (repo.loading) {
return repo.text;
}

var markup = "<div class='select2-result-repository clearfix'>" +
// "<div class='select2-result-repository__avatar'><img src='" + repo.owner.avatar_url + "' /></div>" +
"<div class='select2-result-repository__meta'>" +
"<div class='select2-result-repository__title'>" + repo.text + "</div>";
//if (repo.description) {
// markup += "<div class='select2-result-repository__description'>" + repo.description + "</div>";
//}
markup += "<div class='select2-result-repository__statistics'>" +
"<div class='select2-result-repository__forks'><i class='fa fa-flash'></i> " + repo.name + "--" + repo.depname + " </div>" +
//"<div class='select2-result-repository__stargazers'><i class='fa fa-star'></i> " + repo.stargazers_count + " Stars</div>" +
//"<div class='select2-result-repository__watchers'><i class='fa fa-eye'></i> " + repo.watchers_count + " Watchers</div>" +
"</div>" +
"</div></div>";

return markup;
}

function formatRepoSelection(repo) {
return repo.name || repo.text;
}
