使用键入的角度浮动输入标签
我使用了这里的一种风格:http://tympanus.net/Development/TextInputEffects/index.html
要创建输入指令,请参阅plunker:https://plnkr.co/edit/wELJGgUUoiykcp402u1G?p=preview
这对于标准输入字段非常有用,但是,我正在努力工作,以锻炼Twitter的typeahead:https://github.com/twitter/typeahead.js/
问题 - 如何将我的浮动输入标签用于打字?
app.directive('floatInput', function($compile) {
return {
restrict: 'E',
replace: true,
transclude: true,
scope: {
elemTitle: '=elemTitle',
elemtId: '=elemeId'
},
templateUrl: 'input-template.html',
link: function(scope, elem, attrs) {
var ngModelName = elem.attr('input-model');
var inputElem = angular.element(elem[0].querySelector('input'));
inputElem.attr('ng-model', ngModelName);
$compile(inputElem)(scope);
$compile(inputElem)(scope.$parent);
var inputLabel = angular.element(elem[0].querySelector('label span'));
inputLabel.attr('ng-class', '{'annimate-input' : '+ngModelName+'.length > 0}');
$compile(inputLabel)(scope);
},
controller: function($scope) {
$scope.title = $scope.elemTitle;
$scope.inputId = $scope.elemId
}
}
})
HTML:
<div>
<span class="input input--juro">
<input class="input__field input__field--juro" type="text" id="{{inputId}}" ng-model="tmp" />
<label class="input__label input__label--juro" for="{{inputId}}">
<span class="input__label-content input__label-content--juro">{{title}}</span>
</label>
</span>
</div>
我所知道的最简单的方法是在指令的link
函数中初始化typeahead输入。 为了使用可用选项初始化typeahead,我会为该指令创建一个可选参数,并在提供列表时选择性地将输入初始化为一个typeahead输入。
下面是一个指令如何看起来的例子:
app.directive('floatInput', function($compile) {
return {
restrict: 'E',
replace: true,
transclude: true,
scope: {
elemTitle: '=elemTitle',
elemtId: '=elemeId',
typeaheadSrc: '=?typeaheadSrc'
},
templateUrl: 'input-template.html',
link: function(scope, elem, attrs) {
var inputElem = angular.element(elem[0].querySelector('input'));
if(scope.typeaheadSrc && scope.typeaheadSrc.length > 0){
var typeahead = jQuery(inputElem).typeahead({
hint: true,
highlight: true,
minLength: 1
}, {
name: 'typeahead',
source: substringMatcher(scope.typeaheadSrc)
});
}
},
controller: function($scope) {
$scope.title = $scope.elemTitle;
$scope.inputId = $scope.elemId
}
}
});
// from http://twitter.github.io/typeahead.js/examples/
var substringMatcher = function(strs) {
return function findMatches(q, cb) {
var matches= [],
substrRegex = new RegExp(q, 'i');
$.each(strs, function(i, str) {
if (substrRegex.test(str)) {
matches.push({value: str});
}
});
cb(matches);
};
};
