You may have an infinite update loop in a component render function

Posted 2023-05-10 周紫妍

在组件渲染函数中你可能有一个无限更新的循环

这就导致页面一直在加载无限循环下去，没有终止，卡死

 在 v-for 循环当中，如果用方法或者计算属性对 vm.$data 的属性进行操作，理论上，可能因为修改到循环对象，诱发无限循环。此时 Vue 就会发出警告（并不是真的已经无限循环了）

 

You have ettempted to queue to many files.You may select one files.

<script type="text/javascript" src="/script/swfupload/swfupload.js"></script>
<script type="text/javascript" src="/script/swfupload/swfupload.queue.js"></script>
<script type="text/javascript" src="/script/swfupload/handlers.js"></script>

var swfu = new SWFUpload({
upload_url: "http://www.aa.com/changeFile", // 文件上传 地址
post_params: {"name" : "huliang"},

// File Upload Settings
file_size_limit : "10 MB",// 1000MB
file_types : "*.doc;*.docx",
file_types_description : "文档",
file_upload_limit : "1", // 限制文件上传个数 为 1

file_queue_error_handler : fileQueueError,
file_dialog_complete_handler : fileDialogComplete,//选择好文件后提交
// file_queued_handler : fileQuened,
upload_progress_handler : uploadProgress,
upload_error_handler : uploadError,
upload_success_handler : uploadSuccess,
upload_complete_handler : uploadComplete,
button_action:SWFUpload.BUTTON_ACTION.SELECT_FILE,


// Button Settings
// button_image_url : "images/SmallSpyGlassWithTransperancy_17x18.png",
button_placeholder_id : "uploadfile",
button_width: 180,
button_height: 18,
button_text : ‘<span class="blue">上传</span>‘,
button_text_style : ‘.blue{color:#0099cc;text-align:center;}‘,
button_text_top_padding: 0,
button_text_left_padding: 18,
button_window_mode: SWFUpload.WINDOW_MODE.TRANSPARENT,
button_cursor: SWFUpload.CURSOR.HAND,


// Flash Settings
flash_url : "/script/swfupload/swfupload.swf",


custom_settings : {
upload_target : "divFileProgressContainer"
},
// Debug Settings
debug: false  //是否显示调试窗体
});
// 选择文件后。马上提交
function fileDialogComplete(){
swfu.startUpload();
}
// 文件上传成功后，回调函数
function uploadSuccess(file, serverData){
alert(serverData);
myalert(0,"上传成功",function(){
<span style="color:#ff0000;">var stats = swfu.getStats();
        stats.successful_uploads = 0;
        swfu.setStats(stats);</span>
       
});
}
// 文件上传失败，回调函数
function uploadError(){
myalert(0,"上传失败");
swfu.cleanUp();
}
<pre name="code" class="plain"><span style="color:#ff0000;">当上传 1 个文件后，还想在上传，就会报 文件太多的错误。解决方法例如以下：
var stats = swfu.getStats();
stats.successful_uploads = 0;
swfu.setStats(stats);
这样就能够无限制的上传了。。</span>
