我正在使用AngularJS v1.4.1并且我有以下指令。这是我想工作但现在由于某种原因，当我的页面加载时，指令被调用两次。我检查了我能做的一切，但除了指令不再有效之外，我看不到从现在到现在有什么不同。具体而言，它似乎被调用了两次。
app.directive('pagedownAdmin', ['$compile','$timeout', function ($compile, $timeout) {
var nextId = 0;
var converter = Markdown.getSanitizingConverter();
converter.hooks.chain("preBlockGamut", function (text, rbg) {
return text.replace(/^ {0,3}""" *\n((?:.*?\n)+?) {0,3}""" *$/gm, function (whole, inner) {
return "<blockquote>" + rbg(inner) + "</blockquote>\n";
});
});
return {
require: 'ngModel',
replace: true,
scope: {
modal: '=modal'
},
template: '<div class="pagedown-bootstrap-editor"></div>',
link: function (scope, iElement, attrs: any, ngModel) {
var editorUniqueId;
if (attrs.id == null) {
editorUniqueId = nextId++;
} else {
editorUniqueId = attrs.id;
}
scope.showPagedownButtons = function () {
document.getElementById("wmd-button-bar-" + editorUniqueId).style.display = 'block';
};
var newElement = $compile(
'<div>' +
'<div class="wmd-panel">' +
'<div data-ng-hide="modal.wmdPreview == true" id="wmd-button-bar-' + editorUniqueId + '" style="display:none;"></div>' +
'<textarea ng-click="showPagedownButtons()" data-ng-hide="modal.wmdPreview == true" class="wmd-input" id="wmd-input-' + editorUniqueId + '">' +
'</textarea>' +
'</div>' +
'<div data-ng-show="modal.wmdPreview == true" id="wmd-preview-' + editorUniqueId + '" class="pagedownPreview wmd-panel wmd-preview"></div>' +
'</div>')(scope);
// iElement.html(newElement);
iElement.append(newElement);
var hide = function () {
document.getElementById("wmd-button-bar-" + editorUniqueId).style.display = 'none';
}
var editor = new Markdown.Editor(converter, "-" + editorUniqueId, {
handler: hide
});
// var $wmdInput = iElement.find('#wmd-input-' + editorUniqueId);
var $wmdInput = angular.element(document.getElementById("wmd-input-" + editorUniqueId));
var init = false;
editor.hooks.chain("onPreviewRefresh", function () {
var val = $wmdInput.val();
if (init && val !== ngModel.$modelValue) {
$timeout(function () {
scope.$apply(function () {
ngModel.$setViewValue(val);
ngModel.$render();
});
});
}
});
ngModel.$formatters.push(function (value) {
init = true;
$wmdInput.val(value);
editor.refreshPreview();
return value;
});
editor.run();
}
}
}]);
以下是调用该指令的代码：
<textarea data-pagedown-admin
data-modal="cos"
id="contentText"
name="contentText"
ng-minlength="5"
ng-model="cos.content.text"
ng-required="true"></textarea>
当我通过在“var editorUniqueId”上放置一个断点来调试指令时，我发现它会在那里进行两次。
有没有人有任何想法可能会发生什么？
答案 0 :(得分：0)
我过去做过这件事没有问题：
