我正在尝试使用ng-options填充带有一些数字的选择。这是我的代码：
<!DOCTYPE html>

}

<body>
<div ng-app="myApp" ng-controller="editor">

</select>
<p contenteditable="true" id="content" >

</div>
<script>
var app = angular.module('myApp',[]);
app.controller('editor',function($scope){
$scope.color = "black";
$scope.selectedText = "";
$scope.FontSize = function(start, end) {
var size = [];
for (var i = start; i <= end; i++) {
size.push(i);
}
return size;
};
$scope.changeFont = function(){
var newSpan = "<span id='one' style='font-size:'"+$scope.kys_selected_font+"'> </span>"
$("#one").focus();
$("#content").append();
var spans = document.getElementsByTagName('span');
if($scope.selectedText!=""){
for( i=0;i < spans.length;i++){
for( j=0;j < selectedText.length;j++){
var id = spans[i].id;
var selectedId = $scope.selectedText[j].id;
var text = $("#"+id).clone().children().remove().end().text();
var fontSize = $("#"+id).css("font-size");
var selectedinnerText = $("#"+selectedId).clone().children().remove().end().text();;
if(fontSize == $scope.)
if(id === selectedId){
if(text === selectedinnerText){
if(fontSize == $scope.kys_selected_font){
}
else{
$("#"+id).css("font-size",10+"px");
}
}
else{
var replacer = document.getElementById(id);
var newElement = "<span style='font-size:10px;' id='one4'>"+selectedinnerText+"</span>";
replacer.innerHTML = replacer.innerHTML.replace(selectedinnerText,newElement);
}
}
}
}
}
};
$("span").mouseup(function(){
var range = window.getSelection().getRangeAt(0);
content = range.cloneContents();
var select = content.querySelectorAll('span');
$scope.selectedText = select;
});
});
</script>
</body>
</html>
选择始终为空。
答案 0 :(得分：2)
您尚未关闭控制器。在});功能后添加$scope.changeFont。
另外，请在发布问题之前格式化您的代码。对于试图帮助你的人来说，这是一个噩梦，它可以帮助你找到这样的问题。
修改
在$scope.changeFont功能中，您拥有此行if(fontSize == $scope.)。我认为你希望它是if(fontSize == $scope.FontSize)。我在下面的代码段中对其进行了更改，并填充了<select>。 $scope.changeFont是否按预期工作，我不知道，这不属于这个问题的范围。
此外，在您的HTML中，您需要移动<input> <select>。
