setTimeout() 在 Firefox 中似乎不起作用？

Question

我继承了一个网站！ 它旨在在 IE 中工作，而且似乎只能在 IE 中工作。我现在被要求让该站点在 Firefox 中运行。 我已经修复了大部分错误，没有任何问题，但这个问题让我很难过。

设置超时（fDelayedFunc，1000）；

这行 Javascript 在 IE 中运行良好，但在 Firefox 中函数 fDelayedFunc 从不触发。 我已经删除了 setTimeout 和函数包装器，并尝试将代码作为主函数的一部分运行。 这完全没有任何问题。

涉及很多代码，但这是主要的，但我遇到了麻烦。 如果您想查看更多代码，请告诉我。

            setTimeout(fDelayedFunc, 0);

            //Save the current text box value
            var vCurrentTBValue = vJQElement.val();

            function fDelayedFunc() {

                if (vJQElement.val() == vCurrentTBValue) {
                    alert("test");

                    //Get position list box should appear in
                    var vTop = vJQElement.position().top + 25;
                    var vLeft = vJQElement.position().left;

                    //Had to put a special case in for account due to the position co-ords being wrong. This is due to a css error
                    if (vHiddenFieldToWriteTo == "#ctl00_ContentPlaceHolder1_hfAccountCode") {
                        vTop = vJQElement.position().top + 58;
                        vLeft = vJQElement.position().left + 200;
                    }
                    else {
                        vTop = vJQElement.position().top + 25;
                        vLeft = vJQElement.position().left;
                    }


                    //Create div element
                    var vDivElement = $("<div id='divSearchBox' style='position:absolute; top:" + vTop + ";left:" + vLeft + "; z-index: 40000;'></div>");

                    //Create list box
                    var vListBox = $("<select id='lbResults' tabIndex='" + vJQElement.attr("tabIndex") + "' size='4' style='height:400px;'></select>");


                    //Bind a function to the list box which will select the item via either tab or enter
                    vListBox.bind("keydown", function() {
                        //Check if tab or enter has been pressed
                        if (event.keyCode == 9 || event.keyCode == 13) {
                            //Set hidden value to the selected items code
                            $(vHiddenFieldToWriteTo).val($(vListBox.find(":selected")).val());

                            //Create postback
                            $('#ctl00_ContentPlaceHolder1_wizNewConsignment_btnRefresh').click();
                        }
                        //Check if the up arrow has been pressed at the top of the listbox
                        else if (event.keyCode == 38 && $(vListBox.find(":selected")).val() == $(vListBox.find(":first")).val()) {
                            //Focus back on the search box
                            vElement.focus();
                        }
                    }).bind("dblclick", function() {

Answer 1

尝试这个：

setTimeout(function() { fDelayedFunc(); }, 0);

Answer 2

我从addEventListener("load", () => {code})取出了setTimeout(function () {function1();}, 1500) addEventListener("load", () => {code})

它在 Firefox 中对我有用

Answer 3

试试这个： setTimeout('fDelayedFunc()', 0);
