对象不支持属性或方法“停止” IE

Question

When i click on submit button. I got an error like "Object doesn't support property or method stop " in Internet Explorer but data is successfully added in database.

Here is my code.

function SaveComment(subCommentId, trShowresponseId, tdShowresponseId, startDate, endDate) {
//    alert("");
  debugger;
try {
    var response = document.getElementById("TextBoxResponse~" + subCommentId).value;

    if (response === "") {
        alert("Please Enter Response.");
        return false;
    }
    else {
        //  var isAdvanceComment = 1;
        $("#showloading").show();
        var commentType = 'A';
        var returnReult = dashboards_DiscreteRating.SaveComment(response, subCommentId, commentType, startDate, endDate, 0).value;

        if (returnReult.match("Error")) {
            document.getElementById("spanErrorMessage").innerHTML = returnResponse;

        }
        else {
            document.getElementById(tdShowresponseId).innerHTML = returnReult;

        }
        // document.getElementById(tdShowresponseId).innerHTML = dashboards_DiscreteRating.SaveComment(response, subCommentId, commentType, 0).value;
        document.getElementById("trHiddenTextBox~" + subCommentId).className = "hide";
        document.getElementById("trAddSpan~" + subCommentId).className = "show";
        document.getElementById("TextBoxResponse~" + subCommentId).value = "";
        document.getElementById(trShowresponseId).className = "show";
        $("#showloading").hide();
        window.stop();

    }


}
catch (ex) {
    alert(ex.description);
}}

Answer 1

See https://developer.mozilla.org/en-US/docs/Web/API/Window/stop

The stop() method is not supported by Internet Explorer.

Also: I don't know what you are trying to achieve by calling stop() .

However: you call window.stop(); as the last line in your file. Since you don't rollback in your catch -block or anything, everything before that call (eg writing to database) gets executed and not rolled back

Answer 2

Instead of using window.stop() , return false or call preventDefault on the event object in the form's submit listener – likely wherever you call SaveComment . Something along the lines of:

commentForm.addEventListener('submit', function (e) {
    // …
    SaveComment(…);
    e.preventDefault();
});

The alert here suggests you might already be passing the return value straight through:

alert("Please Enter Response.");
return false;

in which case you should be able to do it here too:

$("#showloading").hide();
return false;

Answer 3

Finally i solved this error by using this .

function SaveComment(subCommentId, trShowresponseId, tdShowresponseId, startDate, endDate) {
//    alert("");
  debugger;
try {
    var response = document.getElementById("TextBoxResponse~" + subCommentId).value;

    if (response === "") {
        alert("Please Enter Response.");
        return false;
    }
    else {
        //  var isAdvanceComment = 1;
        $("#showloading").show();
        var commentType = 'A';
        var returnReult = dashboards_DiscreteRating.SaveComment(response, subCommentId, commentType, startDate, endDate, 0).value;

        if (returnReult.match("Error")) {
            document.getElementById("spanErrorMessage").innerHTML = returnResponse;

        }
        else {
            document.getElementById(tdShowresponseId).innerHTML = returnReult;

        }
        // document.getElementById(tdShowresponseId).innerHTML = dashboards_DiscreteRating.SaveComment(response, subCommentId, commentType, 0).value;
        document.getElementById("trHiddenTextBox~" + subCommentId).className = "hide";
        document.getElementById("trAddSpan~" + subCommentId).className = "show";
        document.getElementById("TextBoxResponse~" + subCommentId).value = "";
        document.getElementById(trShowresponseId).className = "show";
        $("#showloading").hide();
        if ($.browser.msie) { //************** Here is the answer ************
            document.execCommand('Stop'); //************** Here is the answer ***********
        }
        else {
            window.stop();
        }


    }


}
catch (ex) {

    alert(ex.description);
}}

Internet Explorer does not support window.stop() so we can use document.execCommand("Stop") for IE.
