我有一个创建动态标签的脚本，但我的问题是如何在标签上添加最大值？我希望有人可以帮助我。

<script src="http://ajax.googleapis.com/ajax/libs/jquery/1/jquery.min.js"></script>
<script src="http://ajax.googleapis.com/ajax/libs/jquery/1/jquery.js"></script>
	<script type="text/javascript">
	
	var countBox = 1;
		
        function toevoegen() { 
		document.getElementById('labels_span').innerHTML+='<span id="labelnaam'+countBox+'">Labelnaam:<input type="text" name="label_naam['+countBox+']"/></span';
		document.getElementById('labels_span').innerHTML+='<span id="labelomschrijving'+countBox+'"><br/>Labelomschrijving:<input type="text" name="label_omschrijving['+countBox+']"/></br></br></span>';
		document.getElementById('labels_span').innerHTML+='<span id="button'+countBox+'" ><input type="button" value="verwijderen" onclick=\'verwijderen('+countBox+');\'></br></br></span>';
		countBox += 1;
	}
		
	function verwijderen(countBox) { 
		var label1 = "#labelnaam"+countBox;
		var label2 = "#labelomschrijving"+countBox;
		var label3 = "#button"+countBox;
		$(label1).remove();
		$(label2).remove();
		$(label3).remove();
		countBox -= 1;
	}
	</script>

	<form action='' name=''  method='post'>
</br><h4>Label toevoegen<input type='button' value='toevoegen' onclick='toevoegen();'></h4></br>
<div id='labels_span'></div></br>
</br><input type='submit' value='Registreren' name='submit_registreren'>
</form>

检查countbox equal/greater/greater than是否为function toevoegen() { if (countBox > 3) { //can use >=, > or == return; } document.getElementById('labels_span').innerHTML+='<span id="labelnaam'+countBox+'">Labelnaam:<input type="text" name="label_naam['+countBox+']"/></span'; document.getElementById('labels_span').innerHTML+='<span id="labelomschrijving'+countBox+'"><br/>Labelomschrijving:<input type="text" name="label_omschrijving['+countBox+']"/></br></br></span>'; document.getElementById('labels_span').innerHTML+='<span id="button'+countBox+'" ><input type="button" value="verwijderen" onclick=\'verwijderen('+countBox+');\'></br></br></span>'; countBox += 1; }到某个金额，例如

function verwijderen(count) { 
    var label1 = "#labelnaam"+count;
    var label2 = "#labelomschrijving"+count;
    var label3 = "#button"+count;
    $(label1).remove();
    $(label2).remove();
    $(label3).remove();
    countBox -= 1;
}

并将删除功能更改为：

countBox

您正在将verwijderen传递给countBox，然后隐藏功能中的TIMESTAMP(6) WITH LOCAL TIME ZONE变量

如何为动态标签添加最大值？
