我有这个简单的HTML表单
<form enctype="multipart/form-data" class="Mesform">
<textarea maxlength="400" type="text" placeholder="Your message" class="MessageInp"></textarea>
<div class="attach">
<input type="file" id="chatfil" accept="image/*">
<label for="chatfil">
<img src="../img/camera.png" class="addphc">
</label>
</form>
和这个jquery
$("body").delegate('.MessageInp','keydown',function(e) {
if (e.which==13 ) {
$(".Mesform").submit();
}
});
这就是我提交表格的方式
$(".Mesform").submit(function(){
var val=$(this).children('textarea').val();
var who=$(".headChat").text();
var formData = new FormData($(this)[0]);
alert(formData);
if (val!="") {
$.ajax({
url: '../files/ajax.php',
type: 'POST',
data:formData,
success: function (data) {
alert(data)
},
cache: false,
contentType: false,
processData: false
});
}
return false;
});
但我不知道如何用PHP接收这个AJAX调用

为了使表单元素显示在任何请求数组中,例如$_POST
,它们将需要名称属性(name="<something>"
)。例如:
<form enctype="multipart/form-data" class="Mesform">
<textarea name="description" maxlength="400" placeholder="Your message" class="MessageInp"></textarea>
<div class="attach">
<input name="chatfil" type="file" id="chatfil" accept="image/*">
<label for="chatfil">
<img src="../img/camera.png" class="addphc">
</label>
</form>
如上所述,<textarea>
不使用类型。

这样做的一种方法是:
<script>
supportchatinterval = 5000;
$(document).ready(function(){
checkForChangesSupport();
setTimeout(checkForChangesSupport, supportchatinterval);
});
function checkForChangesSupport() {
$.get("getCountSupport.php", function(response) {
if(response == 1) {
refreshTableSupport();
}
setTimeout(checkForChangesSupport, supportchatinterval)
});
}
function refreshTableSupport(){
$('#tableHolderSupport').load('getTableSupport.php');
}
</script>
<script type="text/javascript">
function onBlur(){
document.body.className = 'blurred';
$.get("afk.php?afk=1");
supportchatinterval = null;
clearInterval(supportchatinterval);
};
function onFocus() {
document.body.className = 'focused';
$.get("afk.php?afk=0");
supportchatinterval = 5000;
refreshTableSupport();
}
</script>
