使用Ajax和PHP将数据插入MySQL时，从富文本区域获取有限的数据，有什么问题吗？
JQuery脚本
$('#adddesc').click(function(e)
{
e.preventDefault();
var txtcategoryname=tinyMCE.get('txtcategoryname').getContent();
var txttitle=$('#txttitle').val();
var selectError1=$("#selectError1").val();
var selectError2=$("#selectError2").val();
var selectError3=$("#selectError3").val();
//var fimage=$("#fimage").val();
//alert($("#selectError2").val().length);
var dataString;
var err;
err=(txttitle!='' && txtcategoryname!='' && $("#selectError1").val()!='0' && $("#selectError2").val()!='0' && $("#selectError3").val()!='0')?'0':'1';
// var dataString1="txttitle="+txttitle+"& description="+txtcategoryname+"& catname="+selectError1+"& tags="+selectError2;
//dataString1="txttitle="+txttitle+"& description="+txtcategoryname+"& catname="+selectError1+"& tags="+selectError2+"& subcat="+selectError3;
// alert(dataString1);
if(err=='0')
{
dataString="txttitle="+txttitle+"& description="+txtcategoryname+"& catname="+selectError1+"& tags="+selectError2+"& subcat="+selectError3;
//alert(dataString);
$.ajax({
type: "POST",
url: "aAddDescription.php",
data: dataString,
cache: true,
beforeSend: function(){ $("#adddesc").val('Adding Des.....');},
success: function(html){
//$("#txtcategoryname").val('');
tinyMCE.get('txtcategoryname').setContent('');
$("#txttitle").val('');
//$("#selectError1").get(0).selectedIndex = 0;
//$("#error").removeClass("alert alert-error");
$("#error").addClass("alert alert-success");
$("#error").html("<span style='color:#cc0000'>Success:</span> Description Added Successfully. ").fadeIn().delay(3000).fadeOut();
}
});
HTML表单脚本

$ccount=mysqli_num_rows($cresult);
if($ccount==0)
{
mysqli_query($db,"INSERT INTO counter(cont_id) VALUES(".$cid.")");
}
echo "1";
}
?>
请帮我解决这段代码中的任何错误？...即使我将缓存更改为false也会遇到同样的问题。如果我输入1000 /更少或更多的行数据，它总是采用有限的数据。请帮我。在此先感谢

我愿意打赌你的文字中包含干扰网址的字符，如“＆amp;”，“？”，“/”，“=”等。
您应该使用{{3}}对文字进行编码，如下所示：
var txtcategoryname=encodeURIComponent(tinyMCE.get('txtcategoryname').getContent());
var txttitle=encodeURIComponent($('#txttitle').val());
var selectError1=encodeURIComponent($("#selectError1").val());
var selectError2=encodeURIComponent($("#selectError2").val());
var selectError3=encodeURIComponent($("#selectError3").val());
