推荐答案

好吧，在您将textmode更改为SingleLine之前，我会遇到此问题，您会发现u将对这个问题进行搜索，并且我找不到我在textchange上所做的有用的事情，我将值保存在viewstate上，然后再次对其进行赋值，它和我一起工作
希望对您有帮助
最好的问候

使用以下脚本验证其是否为空

Use the below script to validate whether it is really empty

<script>
function check(value){
if(value=="" || (typeof(value==='number') && value > 0))
alert("The textfield is empty OR its content (value) is a number greater than 0 (> 0)");

}
</script>

<input type="text" onblur="check(this.value)" />
