Visual Studio 2012를 사용하여 웹 응용 프로그램을 작성하고 있습니다. 텍스트 상자에 단어 수를 추가하려고합니다. 그러나 자바 스크립트 코드와 HTML 코드를 추가 한 후. 위에서 설명한대로 오류가 나타납니다.

여기 내 자바 스크립트가 코딩되어 있습니다.

코드 :

function validateLimit(obj, divID, maxchar) {

objDiv = get_object(divID);

if (this.id) obj = this;

var remaningChar = maxchar - trimEnter(obj.value).length;

if (objDiv.id) {
    objDiv.innerHTML = remaningChar + " characters left";
}
if (remaningChar <= 0) {
    obj.value = obj.value.substring(maxchar, 0);
    if (objDiv.id) {
        objDiv.innerHTML = "0 characters left";
    }
    return false;
}
else
{ return true; }
}

function get_object(id) {
var object = null;
if (document.layers) {
    object = document.layers[id];
} else if (document.all) {
    object = document.all[id];
} else if (document.getElementById) {
    object = document.getElementById(id);
}
return object;
}

function trimEnter(dataStr) {
return dataStr.replace(/(\r\n|\r|\n)/g, "");
}
