问题描述
我使用jQuery UI部件 Tagit 在 Asp.net
。代码工作正常,但我想强调这是不可进入名单的标签。
I am using jQuery UI widget Tagit in Asp.net
. Code is working fine but i want to highlight the tags which is not available into the list.
如果我的标签
VAR sampleTags = ['C ++,Java的','PHP','ColdFusion的','的javascript']
和我使用的任何其他文字而无法使用到 sampleTags
如何突出这些标签与其他颜色。
and i am using any other word which is not available into sampleTags
how do i highlight these tags with other color.
我使用下面的代码
JS: -
<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.10.2/jquery.min.js" type="text/javascript" charset="utf-8"></script>
<link href="../CSS/jquery.tagit.css" rel="stylesheet" />
<script src="https://ajax.googleapis.com/ajax/libs/jqueryui/1.9.2/jquery-ui.min.js" type="text/javascript" charset="utf-8"></script>
<script src="../JavaScript/tag-it.js"></script>
<link href="../CSS/tagit.ui-zendesk.css" rel="stylesheet" />
<script>
$(function () {
$.ajax({
url: 'UpdateSingImgKwds.aspx/GetKeywords',
type: 'GET',
datatype: "json",
contentType: "application/json; charset=utf-8",
success: function (res) {
$('#singleFieldTags').tagit({
caseSensitive: false,
availableTags: res.d,
allowSpaces: true,
singleField: true,
singleFieldNode: $('#txtCompKwds'),
beforeTagAdded: function (event, ui) {
if ((res.d).indexOf(ui.tagLabel.toLowerCase()) == -1) {
$(ui.tag).css('background', '#fff1b5')
}
}
});
},
failure: function (err) {
alert(err);
}
});
});
CS代码: -
[WebMethod]
[ScriptMethod(UseHttpGet = true, ResponseFormat = ResponseFormat.Json)]
public static string[] GetKeywords()
{
List<string> lst = new List<string>();
string queryString = "select * from KWD_Library ORDER BY Keyword asc";
using (SqlConnection connection = new SqlConnection(ConfigurationManager.AppSettings["vConnString"].ToString()))
{
using (SqlCommand command = new SqlCommand(queryString, connection))
{
connection.Open();
using (SqlDataReader reader = command.ExecuteReader())
{
while (reader.Read())
{
lst.Add(reader["Keyword"].ToString());
}
}
}
}
return lst.ToArray();
请帮我做this.Thanks提前。
Please help me to do this.Thanks in advance.
推荐答案
使用的 beforeTagAdded
事件,并比较加入 sampleTags
,
Use beforeTagAdded
event and compare the tags added to sampleTags
,
beforeTagAdded: function (event, ui) {
if ($.inArray(ui.tagLabel,sampleTags) == -1) {
$(ui.tag).css('background', 'red')
//you can use `addClass()` here instead of .css()
}
}
Demo Fiddle
$("#singleFieldTags").tagit({
availableTags: sampleTags,
beforeTagAdded: function (event, ui) {
if ($.inArray(ui.tagLabel,sampleTags) == -1) {
$(ui.tag).css('background', 'red')
}
}
});
