Javascript if语句是否可以放在另一个if-else语句中?
我觉得我应该能够从谷歌搜索中找到这个,但是没有,所以我会在这里问 我在第二条if语句中不断遇到错误,因此我想知道是否不允许在预先存在的if/else语句中放置另一条if语句 谢谢你的关注Javascript if语句是否可以放在另一个if-else语句中?,javascript,if-statement,Javascript,If Statement,我觉得我应该能够从谷歌搜索中找到这个,但是没有,所以我会在这里问 我在第二条if语句中不断遇到错误,因此我想知道是否不允许在预先存在的if/else语句中放置另一条if语句 谢谢你的关注 function flipImages(){ currentImage = flipArray[i]; if (i == 6) { clearInterval(interval) } else { // add an opacity animat

您缺少了几个右括号和大括号,或者在错误的位置有一些右括号和大括号。使用带有语法高亮显示的体面编辑器可以很容易地发现这样的错误 对于记录,是的,如果语法正确,则可以嵌套
if
语句
以下是您的代码的更正版本:
function flipImages(){
currentImage = flipArray[i];
if (i == 6) {
clearInterval(interval)
}
else {
// add an opacity animation to the flip so that it is less jarring
// set at a 100ms fade in
$(currentImage).animate({
opacity: 1
}, 100, function() {
console.log(flipArray[i]);
});
// also animate in the child divs of the currentImage (which will only be text on
// the "final" div)
if ($(currentImage).children().hasClass('final')) {
$(currentImage).children().animate({
opacity: 1,
left: '+=50'
}, 500, function(){
console.log( $(currentImage).children() );
});
};
i++;
};
}
在if($(currentImage).children().hasClass('final')之后,你漏掉了a),还漏掉了几个分号,使它成为无效的js
function flipImages() {
currentImage = flipArray[i];
if (i == 6) {
clearInterval(interval);
} else {
// add an opacity animation to the flip so that it is less jarring
// set at a 100ms fade in
$(currentImage).animate({
opacity: 1
}, 100, function () {
console.log(flipArray[i]);
});
// also animate in the child divs of the currentImage (which will only be text on
// the "final" div)
if ($(currentImage).children().hasClass('final')) {
$(currentImage).children().animate({
opacity: 1,
left: '+=50'
}, 500, function () {
console.log($(currentImage).children());
});
}
i++;
}
}
在hasglass('final')之后,您有一个缺少的字符。应该是hasClass('final')。如果允许,您只是有一个语法错误。您缺少一个
