我在错误控制台中收到以下错误,该错误未显示在问题所在的视图源中:
typeError: $(...).text(...).html is not a function
但是通过试图找出错误来自哪里,我认为错误出现在下面的代码中,因为它在我单击取消按钮后出现:
function htmlEncode(value) { return $('<div/>').text(value).html(); }
我在谷歌中找不到这个问题,但有人在我的 jquery 代码中看到错误吗?如果出现错误,代码中的错误可能会导致控制台中的错误。
完整代码:
下面是html编码:
function htmlEncode(value) { return $('<div/>').text(value).html(); }
开始上传功能:
function startImageUpload(imageuploadform){
$(imageuploadform).find('.imagef1_upload_process').css('visibility','visible');
$(imageuploadform).find('.imagef1_cancel').css('visibility','visible');
$(imageuploadform).find('.imagef1_upload_form').css('visibility','hidden');
$(imageuploadform).find('.imagemsg').css('visibility','hidden');
sourceImageForm = imageuploadform;
$(".sbtnimage").attr("disabled", "disabled");
$(".sbtnvideo").attr("disabled", "disabled");
$(".sbtnaudio").attr("disabled", "disabled");
$(imageuploadform).find(".imageCancel").on("click", function(event) {
$('.upload_target_image').get(0).contentwindow;
stopImageUpload(2);
$("iframe[name='upload_target_image']").on("load",function() {
stopImageUpload(1);
}).attr("src", "cancelimage.php");
});
return true;
}
var imagecounter = 0;
停止上传的函数:
function stopImageUpload(success, imagefilename){
var result = '';
imagecounter++;
if (success == 1){
result = '<span class="imagemsg'+imagecounter+'">The file was uploaded successfully</span>';
$('.listImage').eq(window.lastUploadImageIndex).append('<div>' + htmlEncode(imagefilename) + '<button type="button" class="deletefileimage" image_file_name="' + imagefilename + '">Remove</button><br/><hr/></div>');
}
else if (success == 2){
result = '<span class="imagemsg'+imagecounter+'"> The file upload was cancelled</span>';
}
else {
result = '<span class="imagemsg'+imagecounter+'">There was an error during file upload</span>';
}
$(sourceImageForm).find('.imagef1_upload_process').css('visibility','hidden');
$(sourceImageForm).find('.imagef1_cancel').css('visibility','hidden');
$(sourceImageForm).find('.imagemsg').html(result);
$(sourceImageForm).find('.imagemsg').css('visibility','visible');
$(sourceImageForm).find(".fileImage").replaceWith("<input type='file' class='fileImage' name='fileImage' />");
$(sourceImageForm).find('.imagef1_upload_form').css('visibility','visible');
$(".sbtnimage").removeAttr("disabled");
$(".sbtnvideo").removeAttr("disabled");
$(".sbtnaudio").removeAttr("disabled");
$(".imageClear").on("click", function(event) {
event.preventDefault();
$(this).parents("form:first").find(".fileImage").replaceWith("<input type='file' class='fileImage' name='fileImage' />");
});
var _imagecounter = imagecounter;
$('.listImage').eq(window.lastUploadImageIndex).find(".deletefileimage").on("click", function(event) {
var image_file_name = $(this).attr('image_file_name');
jQuery.ajax("deleteimage.php?imagefilename=" + image_file_name)
.done(function(data) {
$(".imagemsg" + _imagecounter).html(data);
});
$(this).parent().remove();
});
return true;
}
ImageclickHandler() 函数:
function imageClickHandler(imageuploadform){
if(imageValidation(imageuploadform)){
window.lastUploadImageIndex = $('.imageuploadform').index(imageuploadform);
return startImageUpload(imageuploadform);
}
return false;
}
更新:
下面是上传文件的php代码:
<?php
ini_set('display_errors', 1);
error_reporting(E_ALL);
session_start();
if ($_FILES['fileImage']['error'] === UPLOAD_ERR_OK) {
$result = 0;
if (getimagesize($_FILES['fileImage']['tmp_name'])) {
if ((($_FILES["fileImage"]["type"] == "image/gif") || ($_FILES["fileImage"]["type"] == "image/jpeg") || ($_FILES["fileImage"]["type"] == "image/pjpeg") || ($_FILES["fileImage"]["type"] == "image/jpg")) && ($_FILES['fileImage']['size'] > 0)) {
if (is_file("ImageFiles/" . $_FILES['fileImage']['name'])) {
$parts = explode(".", $_FILES['fileImage']['name']);
$ext = array_pop($parts);
$base = implode(".", $parts);
$n = 2;
while (is_file("ImageFiles/" . $base . "_" . $n . "." . $ext))
$n++;
$_FILES['fileImage']['name'] = $base . "_" . $n . "." . $ext;
move_uploaded_file($_FILES["fileImage"]["tmp_name"], "ImageFiles/" . $_FILES["fileImage"]["name"]);
$result = 1;
}
else {
move_uploaded_file($_FILES["fileImage"]["tmp_name"], "ImageFiles/" . $_FILES["fileImage"]["name"]);
$result = 1;
}
}
}
} else {
echo "Upload was not successful";
}
?>
<script language="javascript" type="text/javascript">window.top.stopImageUpload(<?php
echo $result;
?>, '<?php
echo $_FILES['fileImage']['name'];
?>');</script>
</body>
</html>
更新 2:
iframe 加载的当前代码:
$(imageuploadform).find(".imageCancel").on("click", function(event) {
$('.upload_target_image').get(0).contentwindow;
stopImageUpload(2);
$("iframe[name='upload_target_image']").on("load",function() {
stopImageUpload(1);
}).attr("src", "cancelimage.php");
iframe 加载的原始代码:
$(imageuploadform).find(".imageCancel").on("click", function(event) {
$('.upload_target_image').get(0).contentwindow;
$("iframe[name='upload_target_image']").on("load",function() {
stopImageUpload(2);
}).attr("src", "cancelimage.php");
原始代码发生的情况是,当文件成功上传时,发生的事情是瞬间显示成功 == 1 消息,但随后立即显示取消消息,即成功 - 2。
这显然是不正确的,所以尝试修复它,我尝试了当前的代码解决方案,所以我认为如果取消,显示成功 == 2 消息,如果文件成功,则显示成功 == 1 消息那条信息没有改变。但是感谢Barman,这导致了我遇到的错误
