如何根据角度js指令限制得到绑定的值：’A’？
<span directiverestrict> {{binding}} </span>
我尝试使用elem [0] .innerText,但它返回精确绑定“{{binding}}”而不是绑定的值
.directive('directiverestrict',function() {
return {
restrict:'A',link: function(scope,elem,attr) {
// I want to get the value of the binding enclosed in the elements directive without ngModels
console.log(elem[0].textContent) //----> returns '{{binding}}'
}
};
});
解决方法
您可以使用$interpolate服务,例如
.directive('logContent',function($log,$interpolate) {
return {
restrict: 'A',link: function postLink(scope,element) {
$log.debug($interpolate(element.text())(scope));
}
};
});
