首先放置一个上传按钮及相关预览信息等
- <form id="upload_form" enctype="multipart/form-data" method="post" action="upload.php" onsubmit="return checkForm()">
-
- <input type="hidden" id="x1" name="x1" autocomplete="off" />
- <input type="hidden" id="y1" name="y1" autocomplete="off" />
- <input type="hidden" id="x2" name="x2" autocomplete="off" />
- <input type="hidden" id="y2" name="y2" autocomplete="off" />
- <input type="file" name="image_file" id="image_file" onchange="fileSelectHandler()" />
- <div class="error">
- 注意:上传前,先截图
- </div>
- <div class="step2">
- <img id="preview" />
- <div class="info">
- <ul>
- <li><label>文件大小</label> <input type="text" id="filesize" name="filesize" class="input" autocomplete="off" /></li>
- <li><label>类型</label> <input type="text" id="filetype" name="filetype" class="input" autocomplete="off" /></li>
- <li><label>图像尺寸</label> <input type="text" id="filedim" name="filedim" class="input" autocomplete="off" /></li>
- <li><label>宽度</label> <input type="text" id="w" name="w" class="input" autocomplete="off" /></li>
- <li><label>高度</label> <input type="text" id="h" name="h" class="input" autocomplete="off" /></li>
- </ul>
- </div>
- <input type="submit" value="上传" class="btn" />
- </div>
- </form>
接着引用js和css样式
- <link href="css/jquery.Jcrop.min.css" rel="stylesheet" type="text/css" />
- <script type="text/javascript" src="jquery.js"></script>
- <script src="js/jquery.Jcrop.min.js"></script>
接着看下表单的检查
- function checkForm() {
- if (parseInt($('#w').val())) //若是没有截屏
- return true;
- $('.error').html('请先选择图片,并且截图').show();
- return false;
- }
上传文件条件设置
- var rFilter = /^(image\/jpeg|image\/png|image\/jpg)$/i;
- if (!rFilter.test(oFile.type)) {
- $('.error').html('请选择jpg、jpeg或png格式的图片').show();
- return;
- }
-
- // check for file size
- if (oFile.size > 1000 * 1024) {
- $('.error').html('请上传小于1M的图片').show();
- return;
- }
