Question

我一直在对我的系统进行编码，我发现在提示中获取按下按钮的值很困难。

这是我在系统中使用的代码。

function confirmme(){
        var ans;
        $.prompt("Open your javascript console to see the answer.", {
            title: "Are you Ready?",
            buttons: { "Yes, I'm Ready": true, "No, Lets Wait": false },
            submit: function(e,v,m,f){
                // use e.preventDefault() to prevent closing when needed or return false. 
                // e.preventDefault(); 
                ans = v;
            }
        });

        if(ans){
            return true;
            alert("Value clicked was: "+ v);
        } else{
            return false;
            alert("Value clicked was: "+ v);
        }
    }

这是我的HTML代码。

<input type="submit" class="add" name="add" id="add-submit" value="ADD" onclick="return confirmme()">

                evt.preventDefault();
                event.returnValue = true;

                event.returnValue = false;

        });

        // new FormValidator();
        validator.registerCallback('check_loan', function(value) {
            if ((value)>=1000) {
                return true;
            }
            return false;
        })
        .setMessage('check_loan', 'Loan Amount must be atleast \&\#8369 1000.');

我在我的代码中使用了validate.js.

Answer 1

问题是确认对话框未阻止，因此单击事件处理程序将在单击确认对话框中的是/否选项之前完成。

所以

<form id="myform" action="">
    <input type="submit" class="add" name="add" id="add-submit" value="ADD" />
</form>

然后

//dom ready handler
jQuery(function () {
    //use the forms submit event instead of the button click also use jQuery events instead of inline handlers
    $('#myform').submit(function (e) {
        var frm = this;

        //by defualt prevent the form submit
        e.preventDefault();

        //do your validation here, if invalid don't show the prompt

        //show the confirm dialog
        $.prompt("Open your javascript console to see the answer.", {
            title: "Are you Ready?",
            buttons: {
                "Yes, I'm Ready": true,
                    "No, Lets Wait": false
            },
            submit: function (e, v, m, f) {
                if (v) {
                    //if confirmed submit the form
                    frm.submit()
                }
            }
        });
    })
})
