当之前输入错误的值时，Javascript验证不起作用

我有一个这样的表单(一个aspx页面):http://prntscr.com/8tmvge。我分别写了验证，运行正常。如果用户在名称文本框(ex)中输入数值，它会给出错误，我正在清除该文本框(仅该文本框)，但输入准确的值并按下发送按钮，没有任何验证和单击事件不会触发。我不明白我怎么才能解决这个问题?代码如下:

顺便说一下，id='content'选择器在另一个页面中。我在给埃克尔装货。当按下' kle'按钮(在ShowRecord.aspx中)时，将其放入div(在ShowRecord.aspx中)。aspx再一次)。错误对话框在ShowRecord中。aspx。
