bootstrap中使用modal加载kindeditor时弹出层文本框不能输入怎么办

$('#myModal').on('shown', function() {
 $(document).off('focusin.modal');
});
//显示modal
$('#myModal').modal('show');
//show完毕前执行
$('#myModal').on('shown', function () {
  //加上下面这句！解决了~
  $(document).off('focusin.modal');
 // 打开Dialog后创建编辑器
 KindEditor.create('textarea[name="content"]', {
  resizeType : 1
 });
})
//hide完毕前执行
$('#myModal').on('hidden', function () {
 // 关闭Dialog前移除编辑器
 KindEditor.remove('textarea[name="content"]');
})

function computeMaskHeight() {
   var obj = $("#blockLoading");
   var parent = obj.parent();
   obj.height(parent.height());
  }
  function block(opt) {
   var defaults = {
    title: "",
    showClose: true,

   };
   var setting = $.extend(defaults, opt);
   $("#blockTitle").html(setting.title);
   if (setting.showClose) {
