Javascript 将ng模型值指定为cakephp select的默认值

我正在使用一个函数来获取名字和姓氏的首字母，它工作正常。我现在面临的问题是我在ng重复中应用了这个函数。由于ng repeat生成的列表中的select没有默认值，因此我在empty属性中获取该值。现在我想将ng模型值指定为默认值。 获取首字母的JS函数：

function getInitials(attrs,element)
{
   if(attrs.ulabel ){  
        var x = $(element).find(":selected").text();                
        console.log(x);
        var seperateWords = x.split(" ");
        var acronym = "";
        for (var i = 0; i < seperateWords.length; i++){
            acronym = (acronym + seperateWords[i].substr(0,1).toUpperCase());
        }

  if(element.parent().parent().find('label').text() ){
               element.parent().parent().find('label').text(acronym);
            } else 
      element.parent().parent().prepend('<label>'+acronym+'</label>');

            }

函数getInitials（属性，元素） { 如果（attrs.ulabel）{ var x=$（元素）.find（“：selected”）.text（）； 控制台日志（x）； var separatewords=x.split（“”）； var首字母缩写=”； for（var i=0；i 查看文件：
