我有一个动态html,我在一个指令中做出来,它包含一个带验证的输入元素。 实施例的HTML产生具有错误消息:在一个指令中生成HTML时,角度setValidity不起作用
<input id="bob" class="personCheckbox" name="bob"
type="checkbox" value="bob"
ng-model="foobar"
validate-foo/>
<span style="color:red" ng-show="myForm.bob.$error.summary">Need Summary</span>
<input type="text" name="summary-bob" id="summary-bob"/>
,使HTML在用于指令的页面的标签:
<div name-check></div>
,使动态HTML该指令,我有一个手表B/C '人' 是从承诺:
app.directive('nameCheck', function($compile){
return {
replace : true,
restrict: 'A',
scope: false,
link: function($scope, $element, $attrs) {
$scope.$watch('people', function(newValue, oldValue) {
var personNames= [];
for(var i=0; i< newValue.length; i++){
personNames.push(newValue[i].drugName);
}
if(personNames.length > 0) {
replaceElement($scope, $element, $compile, personNames.sort());
}
});
}
}
});
的replaceElement功能:
function replaceElement($scope, $element, $compile, peopleNames){
var html= "\<div class='row'>"
+ "\<div class='small-12 columns'>"
+ "\<label>People</label>";
for(var i=0; i < peopleNames.length; i++){
html += "\<div>";
html += "<input id='" + peopleNames[i] + "' ";
html += " class='drugCheckbox' name='" + peopleNames[i] + "' ";
html += " type='checkbox' value='" + peopleNames[i] + "' ";
html += " ng-model='" + peopleNames[i] + "' ";
html += " validate-foo/>";
html += peopleNames[i];
html += "<span style='color:red' ";
html += " ng-show='myForm." + peopleNames[i]
html += ".\$error.summary'>Need Summary</span>";
html += "<input type='text' ";
html += " name='summary-" + peopleNames[i] +"' ";
html += " id='summary-" + peopleNames[i] + "' ";
html += "\</div>";
}
html += "\</div></div>";
var DOM = angular.element(html);
var $e =$compile(DOM)($scope);
$element.replaceWith($e);
}
,做验证的指令:像它应该,但验证不起作用在页面上
app.directive('validateFoo', function(){
return{
restrict: 'A',
require: 'ngModel',
link: function(scope, elem, attr, ctrl) {
ctrl.$parsers.unshift(function (viewValue) {
var id= attr.id;
if(viewValue) {
var val= document.getElementById('summary-' + id).value;
if(val.length == 0) {
ctrl.$setValidity("summary", false);
}
else {
ctrl.$setValidity("summary", true);
return viewValue;
}
}
});
}
}
});
动态HTML制作节目。 当我硬编码一些示例HTML,并使用验证器,它工作正常。 我不明白为什么验证不起作用(错误信息不会显示),当我有从指令产生的HTML?
为什么你需要使用动态HTML?用ng-repeat不能达到同样的效果吗? – 2014-09-28 00:30:15
我也尝试过,并没有奏效。我希望将动态HTML代生成一个指令将工作。 – bmw0128 2014-09-28 00:39:40
