我在这里遗漏了什么或者在将函数参数传递给调用相同函数的setTimeout
时Internet Explorer中是否存在问题?
这将在Internet Explorer中永远运行:
function myFunction(myParam, tries){
if (typeof tries == "undefined"){
tries = 0;
}
tries++;
if (tries < 2){
setTimeout(myFunction, 50, myParam, tries);
}
}
myFunction("something");
有办法解决这个问题吗?

解释和解决方案是in the MDN:
如果需要将参数传递给回调函数,但需要它 在Internet Explorer中工作,它不支持发送附加内容 你可以参数(既不用setTimeout()也不用setInterval()) 包括这个特定于IE的兼容性代码,它将启用 该浏览器中的HTML5标准参数通道功能 两个计时器只需将它插入脚本的开头即可。
if (document.all && !window.setTimeout.isPolyfill) {
var __nativeST__ = window.setTimeout;
window.setTimeout = function (vCallback, nDelay /*, argumentToPass1, argumentToPass2, etc. */) {
var aArgs = Array.prototype.slice.call(arguments, 2);
return __nativeST__(vCallback instanceof Function ? function () {
vCallback.apply(null, aArgs);
} : vCallback, nDelay);
};
window.setTimeout.isPolyfill = true;
}
if (document.all && !window.setInterval.isPolyfill) {
var __nativeSI__ = window.setInterval;
window.setInterval = function (vCallback, nDelay /*, argumentToPass1, argumentToPass2, etc. */) {
var aArgs = Array.prototype.slice.call(arguments, 2);
return __nativeSI__(vCallback instanceof Function ? function () {
vCallback.apply(null, aArgs);
} : vCallback, nDelay);
};
window.setInterval.isPolyfill = true;
}

您需要将函数包装在不需要参数的函数中:
function myFunction(myParam, tries){
if (typeof tries == "undefined"){
tries = 0;
}
tries++;
if (tries < 2){
setTimeout(function() {
myFunction(myParam, tries);
}, 50);
}
}
myFunction("something");
答案 2 :(得分:1)
setTimeout(function(){myFunction(myParam, tries);}, 50);
