如果之前输入了错误的值，则Javascript验证不起作用

Question

Guys I have a form like this(an aspx page): http://prntscr.com/8tmvge . I wrote validations each of them,And it is working properly. If user enter numeric value in name textbox (ex),it gives error and I'm clearing that textbox(only that textbox) but enter the accurate value and pressing send button, none of the validations and click events doesn't triggered.I couldn't understand how can I fix this? code is below:

        {
            autoOpen: false,
            buttons: [{
                text: "OK",
                click: function () { $(this).dialog("close"); }
            }]
        });
    });
});

By the way the id='content' selector is in another page.I'm loading Ekle.aspx into a div(in ShowRecord.aspx) when pressed 'ekle' button(inside ShowRecord.aspx again).ANd error dialog boxes are in ShowRecord.aspx also.

When you clear the textbox, you should change the result value as 1. Your result value just set as 1, when the document is ready. However, if there is something is wrong, you set it as 0, then you never change it as 1.
