javascript函数不工作？

我的脚本中有两个javascript函数myfunction和submitform

<script>
var intervalID = 0;
function myFunction(interval) {
if(interval == 1) {
    if(intervalID != 0) {
        window.clearInterval(intervalID);
        intervalID = 0;
    }
}
else if(intervalID == 0){
    intervalID = window.setInterval(function () {
        getdetails();
        $('.View').load('alert.php').fadeIn("slow");
        }, 1000);
    }
}

function getdetails(){
    $.ajax({
        type: "POST",
        url: "detail.php"
    }).done(function( result ) {
        $("#msg").html( result );
    });
}

function submitform(){
    var comment = $("#comment").val();
    var alertid = $("#alertid").val();
    $.ajax({
            type: "POST",
            url: "analytic.php",
        data:{cmt:comment,alert_id:alertid}
    }).done(function( result ) {
    $("#msg").html( result );
    });
    return false;
}
</script>

<form method = "POST" onsubmit = "return submitform();" >
  <textarea onFocus = "myFunction(1)" onBlur = "myFunction(0)" style="margin: 0px 0px 8.99305534362793px; width: 570px; height: 50px;" rows = "6" cols = "40" id = "comment"></textarea> <br />
  <input type = "hidden" placeholder="Enter Maximium 100 Words" id = "alertid" value = "102" />
  <input  type = "submit" name = "submit" value = "Comment" />
</form>

表单中osubmit事件的submitform函数调用和textarea标记中onfocus和onblur的myfunction调用。 当我调用submitform函数时，myfunction函数停止处理onfocus和onblur事件

只需使用submitform而不是返回submitform

试试这个

<form  onsubmit = "submitform();" >

朋友们，这段代码现在正在运行。 我发现了我的问题。 按如下所示更正代码

 <script>
    var intervalID = 0;
    function myFunction(interval) {
    if(interval == 1) {
        if(intervalID != 0) {
            window.clearInterval(intervalID);
            intervalID = 0;
        }
    }
    else if(intervalID == 0){
        intervalID = window.setInterval(function () {
            getdetails();
            $('.View').load('alert.php').fadeIn("slow");
            }, 1000);
        }
    }

    function getdetails(){
        $.ajax({
            type: "POST",
            url: "detail.php"
        }).done(function( result ) {
            $("#msg").html( result );
        });
    }

    function submitform(){
        var comment = $("#comment").val();
        var alertid = $("#alertid").val();
        $.ajax({
                type: "POST",
                url: "analytic.php",
            data:{cmt:comment,alert_id:alertid}
        });
        return false;
    }
    </script>

    <form method = "POST" onsubmit = "return submitform();" >
      <textarea onFocus = "myFunction(1)" onBlur = "myFunction(0)" style="margin: 0px 0px 8.99305534362793px; width: 570px; height: 50px;" rows = "6" cols = "40" id = "comment"></textarea> <br />
      <input type = "hidden" placeholder="Enter Maximium 100 Words" id = "alertid" value = "102" />
      <input  type = "submit" name = "submit" value = "Comment" />
    </form>

错误控制台中有错误吗？@JeremyJStarcher没有控制台中没有错误。

function submitform(){
    var comment = $("#comment").val();
    var alertid = $("#alertid").val();
    $.ajax({
            type: "POST",
            url: "analytic.php",
        data:{cmt:comment,alert_id:alertid}
    }).done(function( result ) {
    $("#msg").html( result );
    });
}

 <script>
    var intervalID = 0;
    function myFunction(interval) {
    if(interval == 1) {
        if(intervalID != 0) {
            window.clearInterval(intervalID);
            intervalID = 0;
        }
    }
    else if(intervalID == 0){
        intervalID = window.setInterval(function () {
