Javascript 每X秒加载js文件并更新内容
我有一段JS代码,在前端显示数据和数组。看起来像这样:Javascript 每X秒加载js文件并更新内容,javascript,jquery,ajax,Javascript,Jquery,Ajax,我有一段JS代码,在前端显示数据和数组。看起来像这样: var compliments = { complimentLocation: '.compliment', currentCompliment: '', complimentList: { 'morning': mycompliments.morning, 'afternoon': mycompliments.afternoon, 'evening': mycompl
var compliments = {
complimentLocation: '.compliment',
currentCompliment: '',

var _randomIndex = Math.floor(Math.random() * _list.length);

我遗漏了什么?在这种情况下,setInterval不是更有用吗?e、 g.设置间隔(functionToLoadFile,1000);然后将它移出函数toloadfile,并在页面加载时启动它。函数toloadfile是否多次设置了compaids.init,而实际上没有自己做任何事情。。。您对从“mycompliments.js”中获取的数据不做任何处理,只是(重新)定义了“complaid”对象的“init”函数(该函数还有一个区间函数,我认为如果您在“functionToLoadFile”函数中调用它将不是一个好主意),并且您正在每秒调用它。也许你应该用'data'作为参数调用updateCompliment。。。
function functionToLoadFile(){
jQuery.get('js/mycompliments.js', function(data) {
compliments.init = function () {
this.updateCompliment();
this.intervalId = setInterval(function () {
this.updateCompliment();
}.bind(this), this.updateInterval)
}
setTimeout(functionToLoadFile, 1000);
});
}
