2.数据格式

}
]
},

}
],
3.数据处理 因为后端给的数据都是数组 表单有些需要数组有些需要字符串
this.formList = res.data.data.decisionConditionList;
if (this.formList) {
this.formList.forEach(a => {
if (a.inputType == 4 && a.singleton == 0 || a.inputType == 5 && a.singleton == 0) {
this.$set(this.detailForm, a.conditionCode, a.conditionValueList ? a.conditionValueList : [])
} else if (a.inputType == 3) {
var fileImgurl = []
if (a.conditionValueList) {
a.conditionValueList.forEach((item, index) => {
fileImgurl.push(
Object.assign({}, { url: item })
)
})
this.fileImgurl=fileImgurl
}
this.$set(this.detailForm, a.conditionCode, a.conditionValueList ? a.conditionValueList : [])
}
else {
this.$set(this.detailForm, a.conditionCode, a.conditionValueList ? a.conditionValueList.toString() : '')
}
})
}
4.关于图片部分的js
// 上传之前
beforeUpload(file) {
if (!this.checkFileType(file)) {
return false
}
this.$forceUpdate()
},
// 效验文件类型
checkFileType(file) {
let allowTypesSet = new Set(["jpg", "jpeg", "png", "bmp", "pdf"])
let fileType = file.name.replace(/.+\./, "")
if (!allowTypesSet.has(fileType)) {
this.$message({
type: "warning",
message: "不支持该文件类型"
})
return false
}
return true
},
//预览图片
handlePictureCardPreview(file) {
this.dialogImageUrl = file.url;
this.dialogVisible = true;
},
//删除图片
handleRemoveUrl(file, fileList) {
if (fileList.length) {
this.fileImgurl.filter((item, index) => {
if (item.url == file.url) {
this.fileImgurl.splice(index, 1);
}
});
let results = this.fileImgurl.map(n => n.url);
this.formList.forEach(index => {
if (index.inputType == 3) {
this.$set(this.detailForm, index.conditionCode, results)
}
})
} else {
this.formList.forEach(index => {
if (index.inputType == 3) {
this.$set(this.detailForm, index.conditionCode, [])
}
})
this.fileImgurl = []
}
},
// 导入
f_upload(data) {
const formData = new FormData()
formData.append("file", data.file)
this.handlefileUpload(formData)
},
//上传方法
handlefileUpload(formData) {
fileUpload(formData)
.then((res) => {
const { code, msg } = res.data
if (code == 200) {
this.formList.forEach(a => {
if (a.inputType == 3) {
var arr = a.conditionValueList ? a.conditionValueList : [];
arr.push(res.data.data)
this.$set(this.detailForm, a.conditionCode, arr)
}
})
this.fileImgurl.push({ url: res.data.data })
} else {
const title = "操作失败"
const type = "error"
this.$notification(title, type, msg)
}
})
.catch(() => { })
},
4.提交
//提交这里还是要按照上面的格式提交
this.formList.forEach((item, index) => {
this.detailForm.decisionConditionList.push(
Object.assign({},item, { conditionValueList: item.inputType == 4 && item.singleton == 0 || item.inputType == 5 && item.singleton == 0 || item.inputType == 3 ? this.detailForm[item.conditionCode] : [this.detailForm[item.conditionCode]] })
)
})
