<div style=‘ display: none;‘ >
<iframe name ="uploadResponse_attachment" id= "uploadResponse_attachment"></iframe >
<form id ="uploadForm_attachment" action= "<?php echo site_url(‘logistics/upload_chartering_attachment‘) ?>" target= "uploadResponse_attachment" method ="post" enctype= "multipart/form-data">
<input type ="hidden" name="<?php echo $this->security->get_csrf_token_name(); ?>" value= "<?php echo $this->security->get_csrf_hash(); ?>" />
</form >
</div>
对应js页面添加
//上传租船附件
function upload_attachment_chartering()
{
$(‘#attachment_img_notice‘).show();
var file = document.getElementById( "chartering_attachment");
var uploadFormElement = document.getElementById("uploadForm_attachment" );
uploadFormElement .appendChild(file);
document.getElementById("attachment_img_div").innerHTML = ‘<a href="javascript:void(0)" class="btn_blue_26"><span>上传</span></a><input type="file" onchange="upload_attachment_chartering()" name="chartering_attachment" multiple="multiple" id="chartering_attachment">‘;
//提交图片数据
uploadFormElement .submit();
uploadFormElement.removeChild( uploadFormElement.chartering_attachment);
}
//上传成功回掉
function upload_attachment_chartering_callback(file_path)
{
$(".attachment_show_img").attr( ‘src‘,file_path);
$(‘#attachment_image‘).val(file_path);
$(‘#attachment_img_notice‘).hide();

}
//上传失败回掉
