今天小編給大家分享一下vue+element upload上傳帶參數的方法的相關知識點，內容詳細，邏輯清晰，相信大部分人都還太了解這方面的知識，所以分享這篇文章給大家參考一下，希望大家閱讀完這篇文章后有所收獲，下面我們一起來了解一下吧。
<el-button size="small" type="success" @click="submitUpload">保存</el-button>
<el-upload class="upload-demo" ref="upload" :action="action()" :on-preview="handlePreview" :before-upload="beforeUpload" :data="uploadData" :on-error = "error" :on-success="successResave" :on-remove="handleRemove" :file-list="fileList" :auto-upload="false"> <el-button slot="trigger" size="small" type="primary">選取文件</el-button> <!-- <el-button size="small" type="success" @click="submitUpload">上傳到服務器</el-button> --> <!-- <div slot="tip" class="el-upload__tip">只能上傳jpg/png文件，且不超過500kb</div> --> </el-upload>
data里面參數
uploadData:null,
methods里面
action(){
return this.portC+"uplodResultsScore"
},
//上傳
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; //通過返回一個promis對象解決
},
//上傳成功鉤子
successResave(response, file, fileList){
console.log(response)
if(response.code==10001){
alert("保存成功")
this.proType="";
this.mobanname="";
this.value5="";
this.$router.push("/moban")
}
},
//失敗鉤子
error(response, file, fileList){
console.log(response)
},
//選擇家化實效
selectType(val){
console.log(val)
if(val==1){
this.$router.push("/new")
}else{
this.$router.push("/new1")
}
},效果圖
可以看出來 :
http-request="(params) =>beforeMasterPictureUpload(params,‘ruleForm',fileList0)"
http-request 傳遞參數的方法 是可以這樣寫的，其他方法一樣，但是如果寫錯少些可能會導致覆蓋原來的方法。
<el-upload :class="{hidesse:hideUpload0,'avatar-uploader':true}"
multiple action="這里不需要填或者隨便寫"
list-type="picture-card" :before-upload="beforeAvatarUpload"
:on-preview="(params) =>handlePictureCardPreview(params,'ruleForm',fileList0)"
:http-request="(params) =>beforeMasterPictureUpload(params,'ruleForm',fileList0)"
:on-change="(params,fileList) =>onChangeMaster(params,fileList,'ruleForm','fileList0')"
:on-exceed="OnExceed"
:on-remove="(params) =>handleRemove(params,'ruleForm',fileList0,'fileList0')" :limit="5"
:file-list="fileList0" @click="titext">
<i class="el-icon-plus"></i>
</el-upload>下面是JS 接受方法 同樣 我們拿 http-request 這個方法做例子
beforeMasterPictureUpload(params, fromData, prop) {
console.log('----aaaa', this.fileList);
console.log('file', params, fromData, prop);
}大家可以輸出看看結果 是否有拿到你上面傳遞過來的字符串或者是值
HTML標簽
<el-upload :class="{hidesse:hideUpload0,'avatar-uploader':true}"
multiple action="這里不需要填或者隨便寫"
list-type="picture-card" :before-upload="beforeAvatarUpload"
:on-preview="(params) =>handlePictureCardPreview(params,'ruleForm',fileList0)"
:http-request="(params) =>beforeMasterPictureUpload(params,'ruleForm',fileList0)"
:on-change="(params,fileList) =>onChangeMaster(params,fileList,'ruleForm','fileList0')"
:on-exceed="OnExceed"
:on-remove="(params) =>handleRemove(params,'ruleForm',fileList0,'fileList0')" :limit="5"
:file-list="fileList0" @click="titext">
<i class="el-icon-plus"></i>
</el-upload>JS語句
// 主圖上傳之前
beforeAvatarUpload(file) {
console.log('主圖上傳之前:', file)
const idJPG =
file.type === "image/jpeg" || "image/gif" || "image/png" || "image/bmp";

setTimeout(() => {

// this.fileList = [];

console.log(file, fromData, prop)

this.dialogVisible = true;
},
beforeMasterPictureUpload(params, fromData, prop) {
