使用 react-dropzone 上传文件，我想以文件传输或 mbs 数据传输的百分比来实现文件进度。
这是链接：https : //react-dropzone.netlify.com/
onDrop(acceptedFiles, uploadApi) {
const filesToBeSent = this.state.filesToBeSent;
if (acceptedFiles.length) {
if (acceptedFiles[0].type === FileTypeList.TYPE) {
filesToBeSent.push(acceptedFiles);
const formData = new FormData();
formData.append("file", acceptedFiles[0]);
uploadApi(formData).then((response) => {
this.setState({
filesPreview: [],
filesToBeSent: [{}],
showNotification: true,
uploadResponse: response,
});
this.props.fetchHistory();
});
} else {
this.setState({
fileType: true,
});
}
} else {
this.setState({

});
}
}

<div {...getRootProps()} …我写这个脚本来改变textarea的值,但我没有这样做.我的代码出了什么问题？
<html>
<head>
<script type="text/javascript">
document.getElementsByName("status").innerHTML = "hi";
document.getElementsByName("status").title= "hi";
document.getElementsByName("status").placeholder= "hi";
</script>

<body>
<textarea placeholder="What's on your mind?" onfocus="window.UIComposer && UIComposer.focusInstance("c4d981e9a2c98b0483252333");" name="status" id="c4d981e9a2c98b0483252333_input" title="What's on your mind?" class="DOMControl_placeholder UIComposer_TextArea">What's on your mind?</textarea>

下面的html是在<cfdocumentitem type ="header">块中提供的.但输出是空的.
<div class="grid">
<div class="span5">
<div class="span5">
Label1

<div class="span5">
Label2
</div>
<div class="span5">
Data2

<div style="clear:both"></div>
</div>
但是当我删除嵌套的'class ="span5"'div并在那里放一些内容时,它工作正常.在cfdocument中嵌套浮点数有什么问题吗???
我正在尝试编写一个允许用户输入任何单词的程序,然后按下按钮以获得结果.
结果是"你好".
任何人都可以帮我弄清楚为什么在渲染时不会出现结果？
<head>
<meta charset = "utf-8">
<script>
function start() {
var button = document.getElementById("add" );
button.addEventListener( "click", t, false );
}
function t() {
r.innerHTML = "Hello";
window.addEventListener( "load", start, false );
}
</script>
</head>
如果你知道我的代码有什么问题,请帮忙.
'excelFileQuery'包含一个查询.
<cfset spreadsheetAddRows(s, excelFileQuery)>
<cfset spreadsheetAddRows(s,"#volunteeralias# Export Report (#dateformat(now(),'mmmm d, yyyy')# at #timeformat(now(),'h:mm tt')#)",1,1)>
<cfheader name="content-disposition" value="attachment; filename=myexcel.xlsx">
<cfcontent type="application/msexcel" variable="#spreadsheetReadBinary(s)#" reset="true">
但是当生成文件时,查询行会显示,而不是第二行.我做错了吗？

function CheckCallerID(){
$.ajax({
type: 'POST',
url: "code/PHPFILE.php",
data: "",
success: function(data) {
//ajax returns Below HTML CODE
$('#caller').html(data);
if($('#newaddressdetails').html().length==0){
var timmer = setTimeout(CheckCallerID(),50000);
}else{
SaveAddress();
}
}
});
}
PHP文件返回值为True
<div id="newcustomer">Update Found</div>
PHP FILE返回值为False
<div id="newcustomer"></div>
先感谢您.
我想要做的是使用一个确认框，如果用户单击“确定”，则从我的SQL数据库中删除一行。我有一个js函数，用于将值“ delete”发送到同一文件上的php函数，如下所示：
<script>
function myFunction() {
if (confirm("Are you sure you want to delete?") == true) {
document.getElementById("delete").name = "delete";
}else{
return false;
}
}
</script>
用户单击以删除图像的按钮是：
<button onclick="myFunction()">Delete Image</button>
我将值发送到PHP函数，如下所示：
<input type="hidden" name="" value="delete" id="delete">
这是我的PHP函数：
if(isset($_POST['delete'])){
$img_path=$_POST['ipath'];
$imgid=$_POST['imgid'];
$link = mysqli_connect($host, $username, $password, $db);
$delete = "DELETE FROM images_info
WHERE Image_Id = $imgid";
$result3 = mysqli_query($link, $delete);
echo "Image Deleted : $imgid";
mysqli_close($link);
}
我究竟做错了什么？我相信这与javascript有关
