这是我的法典,我担心某些变量没有适当范围。

                document.getElementById( number ).value =  48372605629 ;
                emailData.data.value = h;
            }

            function alertYea8() {
                document.getElementById( remember ).innerHTML = ( <h3>Times up partner, what were they?</h3></br><input name="nine" id="nine" type="text"></input></br><p id="send"></p><input id="answer" name="submit" type="button" onclick="finals()" value="Next"/> );
                document.getElementById( number ).value =  no cheating... ;

                }
            function finals() {
                var i = document.getElementById( i ).innerHTML = (document.getElementById("nine").value);
                document.getElementById( remember ).innerHTML = ( <div id="send"><form action="mailto:hubridnoxx@gmail.com" method="POST" enctype="text/plain" name="emailData"></br><input id="data" type="text" size="20" name="data"><br><input type="submit" value="Submit and continue to letters!"></form></div> );

                emailData.data.value = a + b + c + d + e + f + g + h + i;
                var total= 0;
                $( input ,  #email ).each(function () {
                    total += parseInt($(this).val());
                });
                emailData.data.value = total;
                }
            </script>

        </div>
    </body>
</html>

The problem lies in the last line,

emailData.data.value = a + b + c + d + e + f + g + h + i; The page only returns the value of input id i, not input ids a-h. Instead, it displays like tons of [object HTMLInputElement] for each input id value. I m even calling .value. How can I fix this so that

emailData.data.value = a + b + c + d + e + f + g + h + i; displays a set of respective values instead?

Answer 1

您只应当使用一个<代码>var的声明。因此,正如:

var a = document.getElementById("a").value,
    b = document.getElementById("b").value; // and so on

You could also simplify your code a lot with jQuery if you wanted to so you don t have to use document.getElementById so much (or make a shorter variable for document.getElementById)

var a = $("#a").val(),
    b = $("#b").val();
...
function alertMsg(){
  $("#remember").html("...");
}

您还再次在另一个范围内澄清了你的一些全球变量,并试图获取/制定案文投入的<代码>inner Rainbow/code>。这不会奏效。

function changeSet(){
 var a = ...; // <- this line and others in other functions
}
