作为angularjs指令的初学者,我很困惑。以下任何人都可以帮助我。以下是我的自定义指令。
app.directive('customCharts', ['$compile', function($compile) {
return {
restrict: 'EA',
scope: {
dashboard1Data: '=',
title1Text: '=',
dashboard2Data: '=',
title2Text: '=',
},
link: function(scope, element, attrs) {
var template = '<div class="col1"> <p class="graphtitle"> {{title1Text}}</p> <c3-simple id="dashboard1Data" config="dashboard1Data"></c3-simple> </div>' + ' <div class="col2"> <p class="graphtitle"> {{title2Text}}</p> <c3-simple id="dashboard2Data" config="dashboard2Data"></c3-simple> </div> ';
var parent = angular.element(document.querySelectorAll('.customChartsDiv')) // DOM element where the compiled template can be appended
var linkFn = $compile(template);
var content = linkFn(scope);
parent.append(content);
}
}
}]);
我希望我的模板为template = templateFromController
。即,我不想在指令中硬编码我的模板。相反,我想在ng-init函数调用期间在控制器中形成模板,我希望我的指令使用该模板。我该怎么办?
所以在我的控制器中,我会遇到一些事情,
var templateFromController = '<div class="col1"> <p class="graphtitle"> {{title1Text}}</p> <c3-simple id="dashboard1Data" config="dashboard1Data"></c3-simple> </div>'
+' <div class="col2"> <p class="graphtitle"> {{title2Text}}</p> <c3-simple id="dashboard2Data" config="dashboard2Data"></c3-simple> </div> '
+ '<div class="col1"> <p class="graphtitle"> {{title3Text}}</p> <c3-simple id="dashboard3Data" config="dashboard3Data"></c3-simple> </div>'
+' <div class="col2"> <p class="graphtitle"> {{title3Text}}</p> <c3-simple id="dashboard4Data" config="dashboard4Data"></c3-simple> </div> ';
或
var templateFromController = '<div class="col1"> <p class="graphtitle"> {{title1Text}}</p> <c3-simple id="dashboard1Data" config="dashboard1Data"></c3-simple> </div>'
+' <div class="col2"> <p class="graphtitle"> {{title2Text}}</p> <c3-simple id="dashboard2Data" config="dashboard2Data"></c3-simple> </div> ';
这样的东西,基于控制器的ng-init函数调用中的一些其他标准,我将形成我的var templateFromController
,我希望我的自定义指令将此templateFromController用于其模板。任何人都可以帮我做吗?
@Daniel,我根据你的建议做了以下修改:
app.directive('customCharts', ['$compile', function($compile) {
return {
restrict: 'EA',
scope: {
dashboard1Data: '=',
title1Text: '=',
dashboard2Data: '=',
title2Text: '=',
template: '='
},
link: function(scope, element, attrs) {
var parent = angular.element(document.querySelectorAll('.customChartsDiv')) // DOM element where the compiled template can be appended
var linkFn = $compile(template);
var content = linkFn(scope);
parent.append(content);
}
}
}]);
在控制器中:
var template = '<div> </div>';
$scope.init = function() {
template = '<div class="col1"> <p class="graphtitle"> {{title1Text}}</p> <c3-simple id="dashboard1Data" config="dashboard1Data"></c3-simple> </div>';
}
在我的jsp中,我有:
<div class="customChartsDiv">
<div custom-charts dashboard1-data="dashboard1Data" title1-text="title1Text" dashboard2-data="dashboard2Data" title2-text="title2Text" template="template"></div>
</div>
但是它给出了错误:我的指令的行var linkFn = $compile(template);
没有定义模板。
答案 0 :(得分:1)
您可以将其定义为指令中的属性,然后传入对象/字符串(在控制器中创建的对象)。
app.directive('customCharts', ['$compile', function($compile) {
return {
restrict: 'EA',
scope: {
dashboard1Data: '=',
title1Text: '=',
dashboard2Data: '=',
title2Text: '=',
template: '='
},
link: function(scope, element, attrs) {
var parent = angular.element(document.querySelectorAll('.customChartsDiv')) // DOM element where the compiled template can be appended
var linkFn = $compile(scope.template);
var content = linkFn(scope);
parent.html('').append(content);
}
}
}]);
