我製作了一個div,我想讓它在每個1秒的特定方向上生成動畫。在我提供的代碼中有一個名爲resetPosition()
的函數,請不要擔心,它來自我在頭部鏈接的其他js
文件(完美地工作)。我只想知道爲什麼setInterval()
無法正常工作?
這裏是我的代碼: -爲什麼我的setInterval函數不能再次工作? (JavaScript)

這裏的easyJs: -
function element(elementId){
this.myElement = document.getElementById(elementId);
this.resetColor = changeColor;
this.resetSize = changeSize;
this.resetBackground = changeBackground;
this.resetPosition = changePosition;
this.resetBorder = changeBorder;
this.resetFontFamily = changeFont;
this.resetFontSize = changeFontSize;
this.resetFontStyle = changeFontStyle;
this.resetZindex = changeZindex;
this.resetClass = changeClass;
this.resetTitle = changeTitle;
this.resetMarginTop = changeMarginTop;
this.resetMarginLeft = changeMarginLeft;
this.resetSource = changeSource;
this.resetInnerHTML = changeInnerHTML;
this.resetHref = changeHref;
this.resetTextDecoration = changeTextDecoration;
this.resetFontWeight = changeFontWeight;
this.resetCursor = changeCursor;
this.resetPadding = changePadding;
this.getValue = getTheValue;
this.getName = getTheName;
this.getHeight = getTheHeight;
}
function changeColor(color){
this.myElement.style.color = color;
}
function changeSize(height, width){
this.myElement.style.height = height;
this.myElement.style.width = width;
}
function changeBackground(color){
this.myElement.style.background = color;

}
function changeBorder(border){
this.myElement.style.border = border;
}
function changeFont(fontName){
this.myElement.style.fontFamily = fontName;
}
function changeFontSize(size){
this.myElement.style.fontSize = size;

控臺是否顯示任何內容?你檢查過javascript是否失敗了嗎? – AtanuCSE
'setInterval'工作正常,問題出在你的'element'類 –
div只移動一次,控制檯不顯示任何東西! –
