我不知道如何修复此问题,并且我看不到存在此问题的某些装置。我希望有人能帮我
这是我的Javascript代码:

好的,从stacktrace判断,它是这样说的; -
currVal=$(this.val())中的$(this.val())返回的值代码>在某个索引处未定义,或
-$处的地址
中的一个索引的值。每个(地址、函数(索引、当前值)
都未定义
确保$中的索引值。每个(地址,函数(索引,currVal){
都没有超出地址
的长度,并且地址
中的所有元素都分配了一个值
我猜您试图对数组address
中的一个地址进行地理编码,它试图将该地址设置为小写字符串,但找不到字符串
如果address
不是数组,将其设置为数组,它不应该是字符串您使用哪个浏览器来测试?检查chrome中的元素,在显示此错误的行的左侧应该有一个箭头,单击该箭头以展开stacktrace将stacktrace作为问题的一部分放在此处,也就是说,如果您无法重新读取d一个stacktrace,否则它应该告诉您代码中的确切位置wrong@pythonian29033添加了stacktrace.put此代码:警报(地址);
直接在以下行之后:$.getJSON(“/Dashboard/LoadWorkerList”),函数(地址){
并将结果粘贴到问题中…@pythonian29033谢谢谢谢谢谢你能帮我吗?
