Grails - jQuery 自动完成多个值
Grails - jQuery Autocomplete with Multiple Values
单值自动完成工作正常(.) but when I tried the jQuery UI's multiple value example,它没有获得我需要的来源。
这是我的控制器。
def courseList = {
def cList = Course.withCriteria {
ilike 'course', params.term +'%'
}
render (cList.'course' as JSON)
}
这是我的 _form 视图。
<div class="fieldcontain ${hasErrors(bean: studentInstance, field: 'courses', 'error')} required" >
<label for="course">
<g:message code="student.courses.label" default="Courses" />
<span class="required-indicator">*</span>
</label>
<g:textField name="course" id="coursetags" required="" value="${course?.course}"/>
这是我的 jQuery 脚本(完全来自 jQuery UI 演示)。
function split( val ) {
return val.split( /,\s*/ );
}
function extractLast( term ) {
return split( term ).pop();
}
var courses = ["English", "Music", "Science"];
$( "#coursetags" )
// don't navigate away from the field on tab when selecting an item
.bind( "keydown", function( event ) {
if ( event.keyCode === $.ui.keyCode.TAB && $( this ).autocomplete( "instance" ).menu.active ) {
event.preventDefault();
}
})
.autocomplete({
minLength: 2,
source: function( request, response ) {
// delegate back to autocomplete, but extract the last term
response( $.ui.autocomplete.filter( courses, extractLast( request.term ) ) );
},
focus: function() {
// prevent value inserted on focus
return false;
},
select: function( event, ui ) {
var terms = split( this.value );
// remove the current input
terms.pop();
// add the selected item
terms.push( ui.item.value );
// add placeholder to get the comma-and-space at the end
terms.push( "" );
this.value = terms.join( ", " );
return false;
}
});
当脚本中有 var courses
标记时,多值自动完成功能起作用。我如何将自动完成的源连接到我的控制器?
对于单个值,这是我在脚本中的值。
$("#coursetags").autocomplete({
source: "/myApp/student/courseList",
minLength: 2
});
提前致谢。
我找到了这个演示。 https://github.com/jquery/jquery-ui/blob/master/demos/autocomplete/multiple-remote.html
source: function( request, response ) {
$.getJSON( "/myApp/student/courseList",
{term: extractLast( request.term )},
response );},
我替换了 source
部分,现在可以使用了。
