element upload上传带参数
保存
选取文件
data里面参数
uploadData:null,
methods里面
action(){
return this.portC+"uplodResultsScore"
},
//上传
submitUpload() {
this.$refs.upload.submit();
},
handleRemove(file, fileList) {
console.log(file, fileList);
},
handlePreview(file) {
console.log(file);
},
beforeUpload (file) {
this.uploadData = {dstype:this.proType,name:this.mobanname,dsmark:this.value5,};
console.log(this.uploadData)
let promise = new Promise((resolve) => {
this.$nextTick(function () {
resolve(true);
});
});
return promise; //通过返回一个promis对象解决
},
//上传成功钩子
successResave(response, file, fileList){
console.log(response)
if(response.code==10001){
alert("保存成功")
this.proType="";
this.mobanname="";
this.value5="";
this.$router.push("/moban")
}
},
//失败钩子
error(response, file, fileList){
console.log(response)
},
//选择家化实效
selectType(val){
console.log(val)
if(val==1){
this.$router.push("/new")
}else{
this.$router.push("/new1")
}
},
效果图
element上传函数带参数,自定义传参
下面这是标签
可以看出来 :
http-request="(params) =>beforeMasterPictureUpload(params,‘ruleForm',fileList0)"
http-request 传递参数的方法 是可以这样写的，其他方法一样，但是如果写错少些可能会导致覆盖原来的方法。
下面是JS 接受方法 同样 我们拿 http-request 这个方法做例子
beforeMasterPictureUpload(params, fromData, prop) {
console.log('----aaaa', this.fileList);
console.log('file', params, fromData, prop);
}
大家可以输出看看结果 是否有拿到你上面传递过来的字符串或者是值
我将源码放上
HTML标签
JS语句
// 主图上传之前
beforeAvatarUpload(file) {
console.log('主图上传之前:', file)
const idJPG =
file.type === "image/jpeg" || "image/gif" || "image/png" || "image/bmp";
if (!idJPG) {
this.$message.error(
'123123'
);
}
return idJPG;
},
// 图片触发
onChangeMaster(file, fileList, fromData, prop) {
// fileList 当前上传框的数据
switch (prop) {
case 'fileList0':
{ this.hideUpload0 = fileList.length >= this.limitCount; }
break;
case 'fileList1':

console.log('判断一次', file, fileList, this.fileList0)
if (this.inde > 0) {
return
} else {
//let existFile = fileList.slice(0, fileList.length - 1).find(f => f.name === file.name)
//if (existFile) {
// this.inde++
// console.log(existFile)
// this.$message.error(
// '图片重复' + existFile.name

this[prop] = fileList
}
},
// 图片个数超出限制
OnExceed(file, fileList) {
this.$message.error(
'每个选项最多上传5张', "error"
);
},
handleRemove(params, fileList, prop, item) {
prop.forEach((obj, index) => {
console.log(index, obj)
if (params.uid == obj.uid) {
prop.splice(index, 1)
}
})
console.log('删除后的数组', prop);
setTimeout(() => {
switch (item) {
case 'fileList0':

break;

console.log(prop.length >= this.limitCount)
}, 1000)
// this.fileList = [];
this.dialogImageUrl = '';
},
handlePictureCardPreview(file, fromData, prop) {
console.log(file, fromData, prop)
this.dialogImageUrl = file.url;
