我有一个HTML模板,我将其用于角度指令。我需要在编译后在HTML模板上激活一些javascript(我需要触发jQuery步骤以使HTML成为向导)
示例指令HTML:
<div class='example'>{{passThrough.value1}}</div>
我的角度指令是
app.directive('accountWizard', function () {
return {
templateUrl: '../Scripts/angular/directives/templates/AccountWizard.html',
replace: true,
transclude: true,
scope: {
passThrough: "="
},
link: function (scope, elem, attr) {
scope.bindAccountDirective();
}
};
});
主页面中的HTML类似于
<account-wizard pass-through="angularObject"/>
我的问题是,HTML指令在渲染时只有&#34; {{passThrough.value1}}&#34;作为div标签内的文本,它实际上并没有编译角度对象并返回其值。
在Chrome中进行调试时,我可以看到角度对象&#39; passThrough&#39;在链接函数的scope参数中。
我知道我需要在link函数中做一些事情来编译和渲染指令,但是我无法找到它需要的东西。
我需要的只是一个简单的&#39;你需要使用它......&#39;我将从Angular文档中找出如何做到这一点。
基本上,让我们说passThrough.value1 = Test Value
,我需要将我的指令HTML编译为
<div class='example'>Test Value</div>
然后,我需要在渲染角度对象后在HTML上运行jQuery步骤函数
P.S。 scope.bindAccountDirective()函数是用于触发jQuery步骤的包装器方法。
$scope.bindAccountDirective = function () {
$("#frmShippingAccount.wizard-big").steps({
bodyTag: "fieldset",
transitionEffect: "slideLeft",
onStepChanging: function (event, currentIndex, newIndex) {
// Always allow going backward even if the current step contains invalid fields!
if (currentIndex > newIndex) {
return true;
}
var form = $(this);
// Clean up if user went backward before
if (currentIndex < newIndex) {
// To remove error styles
$(".body:eq(" + newIndex + ") label.error", form).remove();
$(".body:eq(" + newIndex + ") .error", form).removeClass("error");
}
// Disable validation on fields that are disabled or hidden.
form.validate().settings.ignore = ":disabled,:hidden";
// Start validation; Prevent going forward if false
return form.valid();
},
onFinishing: function (event, currentIndex) {
var form = $(this);
// Disable validation on fields that are disabled.
// At this point it's recommended to do an overall check (mean ignoring only disabled fields)
form.validate().settings.ignore = ":disabled";
// Start validation; Prevent form submission if false
return form.valid();
},
onFinished: function (event, currentIndex) {
var form = $("#frmShippingAccount");
$("#savePrompt h1").text("Saving...");
$scope.saveShippingAccount($scope.shippingAccount);
}
}).validate({
framework: 'bootstrap',
icon: {
valid: 'glyphicon glyphicon-ok',
invalid: 'glyphicon glyphicon-remove',
validating: 'glyphicon glyphicon-refresh'
},
errorPlacement: function (error, element) { }
});
}
更新的解决方案
在链接功能中使用$timeout()
非常有效。它等待AngularJS呈现passThrough
对象作为其值,然后然后触发bindAccountDirective()
函数。
app.directive('accountWizard', function ($timeout) {
return {
templateUrl: '../Scripts/angular/directives/templates/AccountWizard.html',
replace: true,
scope: {
passThrough: "="
},
link: function (scope, elem, attr) {
$timeout(function(){ scope.bindAccountDirective() }, 0 false);
}
};
