<script> 
 export default {
 props: ["dialogFormVisible","form","formTitle"],
 data() {
 return {
 unChange: true,
 preForm: JSON.parse(JSON.stringify(this.form)) //深拷贝对象
 };
 },
 watch: {
 form:{
 handler:function(nowVal,oldVal){
 var $this = this;
 for(let i in $this.form){
 if(nowVal[i] != $this.preForm[i]) {
 $this.unChange = false;
 break;
 }else {
 $this.unChange = true;
