Question

我有一个表单，我想上传图片和视频，并且必须填写一些信息。在完成表单之前，提交按钮被禁用，在完成视频和图像上传并且所有字段都已填写后，必须启用它。

$("#uploadify").uploadify({
  height        : 30,
  swf           : urljs+'/public/js/uploadify.swf',
  uploader      : urljs+'/public/js/uploadify.php',
  folder        : "../../../uploads",
  width         : 120,
  fileSizeLimit : '200000KB',
  fileTypeDesc  : 'Video Files',
  fileTypeExts  : '*.*;',
  formData      : {
     folder : '../../private/<?php echo $userId;?>'
  },
  onUploadSuccess : function(file, data, response) {
      $("[name=coursebanner]").val(file.name);
      $("[name=banner]").attr("src",'<?php echo base_url();?>private/<?php echo $userId;?>/'+file.name);
  }
});
$(".filedtls").hide();
$("#contentupload").uploadify({
    height        : 30,
    swf           : urljs+'/public/js/uploadify.swf',
    uploader      : urljs+'/public/js/uploadify.php',
    folder        : "../../../uploads",
    width         : 120,
    fileSizeLimit : '40MB', 
    fileTypeDesc  : 'Video Files',
    fileTypeExts  : '*.*;',
    formData      : {
       folder : '../../private/<?php echo $userId;?>/beforeconvert',
       folder1 : '../../private/<?php echo $userId;?>',
       userId : <?php echo $userId?>
    },
    'onComplete': function(event, queueID, fileObj, response, data) {       
   console.log(response);
 },
 'onUploadSuccess' : function(file, data, response) {
        $("[name=promovideoname]").val(file.name);
    }
  });


   $('#createcoursebasicform > input').keyup(function() {

    var empty = false;
    $('#createcoursebasicform > input').each(function() {
        if ($(this).val() == '') {
            empty = true;
        }
    });

    if (empty) {
        $('#save').attr('disabled', 'disabled');
    } else {
        $('#save').removeAttr('disabled');
    }
});

Answer 1

我总是使用JavaScript来禁用和启用提交按钮。

<强> HTML

<input type="submit" id="switch" value="xxxx" disabled="disabled" />

您可能希望在上传完成后传递标记。说Finish，并将其放在Json中，然后您可以使用AJAX从服务器获取Finish。

的JavaScript

 $.ajax({
  url: "test.php",
  dataType: "json", 
  success: function(data){ 
    data.Finish ? $switch.attr('disabled', true) : $switch.removeAttr('disabled');
  }
});

Answer 2

您可以使用带有Ajax调用的jQuery来提交和使用：

 beforeSend

禁用提交按钮！

Answer 3

当您从用户处获取$ _post或$ _get请求时，请使用html代码以下禁用按钮

 <input type="Submit" value="Upload" <?php echo $disable; ?> />

$ if（$ _ post）或get语句的禁用值是NUll或''。如果条件使用$ disable ='disabled';

上传所有文件和数据，当你达到EOF时，$ disable = Null。

如何在上传视频之前禁用按钮？
