我试图让这个ajax工作,但它没有返回任何东西!我已经尝试了很长一段时间,但是我很难过。我得不到任何回报。
我使用PHP生成下面的HTML和Ajax,所以这里是生成Ajax的脚本的输出,但是不起作用。
<div id='imageOptionsDiv1' name='imageOptionsDiv1'>
<p>Convert This Image</p>
<p>Specify Filename: <input type="text" id='userphotofilename1' name='userphotofilename1' value='HonestRepairSmallLogo_png'>
<select id='photoextension1' name='photoextension1'>
<option value="">Select Format</option>
<option value="jpg">Jpg</option>
<option value="bmp">Bmp</option>
<option value="png">Png</option>
</select></p>
<p>Width and height: </p>
<p><input type="number" size="4" value="0" id='width1' name='width1' min="0" max="10000"> X <input type="number" size="4" value="0" id="height1" name="height1" min="0" max="10000"></p>
<p>Rotate: <input type="number" size="3" id='rotate1' name='rotate1' value="0" min="0" max="359"></p>
<input type="submit" id='convertPhotoSubmit1' name='convertPhotoSubmit1' value='Convert Image'>
<script type="text/javascript">
$(document).ready(function () {
$('#convertPhotoSubmit1').click(function() {
var rot = $('rotate1').val();
var wid = $('width1').val();
var hgt = $('height1').val();
var pext = $('photoextension1').val;
var upfn = $('userphotofilename1').val;
$.ajax({
url: 'convertCore.php',
type: "POST",
data: {
rotate:rot,
width:wid,
height:hgt,
photoextension:pext,
userphotofilename:upfn},
success: function(data) {
alert("convertGui2.php"); },
error: function(data) {
alert("Cannot convert this file!"); }
});
});
});
</script>
</div>
根据要求,以下是生成上述代码的PHP部分....
if (in_array($extension, $ImageArray1)) {
?>
<div id='imageOptionsDiv<?php echo $ConvertGuiCounter1; ?>' name='imageOptionsDiv<?php echo $ConvertGuiCounter1; ?>' style="max-width:750px; display:none;">
<p style="max-width:1000px;"></p>
<p>Convert This Image</p>

<select id='photoextension<?php echo $ConvertGuiCounter1; ?>' name='photoextension<?php echo $ConvertGuiCounter1; ?>'>
<option value="">Select Format</option>
<option value="jpg">Jpg</option>
<option value="bmp">Bmp</option>
<option value="png">Png</option>
</select></p>
<p>Width and height: </p>

<p>Rotate: <input type="number" size="3" id='rotate<?php echo $ConvertGuiCounter1; ?>' name='rotate<?php echo $ConvertGuiCounter1; ?>' value="0" min="0" max="359"></p>
<input type="submit" id='convertPhotoSubmit<?php echo $ConvertGuiCounter1; ?>' name='convertPhotoSubmit<?php echo $ConvertGuiCounter1; ?>' value='Convert Image' onclick="toggle_visibility('loadingCommandDiv');">
<script type="text/javascript">

var hgt = $('#height<?php echo $ConvertGuiCounter1; ?>').val();
var pext = $('#photoextension<?php echo $ConvertGuiCounter1; ?>').val;
var upfn = $('#userphotofilename<?php echo $ConvertGuiCounter1; ?>').val;
$.ajax({

帖子需要转到convertCore.php,其中包含一堆使用命令行工具转换文件的意大利面。内部PHP脚本没有增量器。仅需要增量来区分页面上的不同GUI元素。可以在https://github.com/zelon88/HRConvert2

它没有返回任何内容,因为jQuery不知道这个$('rotate1').val();
与...有关...
如果它是你到达的ID,那么你需要在id的前面放置id符号#
。像这样......
$('#rotate1').val();
同样,如果它是您尝试获取的名称属性,请尝试使用此...
$('input[name="rotate1"]').val();
为每个标签添加相关标签;选择,输入等
<强>更新强>
确保在Ajax数据调用中,您在键:值对中设置了正确的键。密钥应该反映元素的name属性,因为这是我们用php交换信息的地方。
因此,在Ajax的数据参数中,对应该看起来像:
rotate1:rot,
width1:wid,
height1:hgt,
photoextension1:pext,
userphotofilename1:upfn
