问题描述
我继承了一个网站！它被设计为在IE中工作，只有IE似乎......我现在被要求让网站在Firefox中运行。我已经修复了大部分的bug而没有任何问题，但这个让我感到难过。
I have inherited a website! which was designed to work in IE and only IE it seems.. I've now been asked to make the site run in Firefox. I've fixed most of the bugs without any problems but this one has me stumped.
setTimeout（fDelayedFunc，1000）;
setTimeout(fDelayedFunc, 1000);
这行Javascript在IE中运行良好但在Firefox中运行良好函数fDelayedFunc永远不会触发。我已经删除了setTimeout和函数包装器，并尝试将代码作为main函数的一部分运行。这完全没有任何问题。
This line of Javascript, works fine in IE but in Firefox the function fDelayedFunc never fires. I've removed the setTimeout and the function wrapper and tried running the code as part of the main function. This works without any problems at all.
有很多代码涉及，但这里是主要但我遇到了麻烦。如果您想再看到代码，请告诉我。
There is alot of code involved but here's the main but I'm having trouble with. If you'd like to see anymore of the code please let me know.
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() {
//Set hidden value to the selected items code

//Set hidden value to the selected items code

}
//Add list box to div
vDivElement.append(vListBox);
//Check if any results exist in div
if (vNumberOfResults != 0) {
//Append div to page
$("body").append(vDivElement);
//Auto select first item
vListBox.find(".AddressOption:first").attr("selected", "true");
}
}
//Hide loading image
vJQElement.css("backgroundImage", "none");
},
error: function(XMLHttpRequest, textStatus, errorThrown) {
//Inform user of error
alert("An error occured, please try again");
//Hide loading image
vJQElement.css("backgroundImage", "none");
}
});
}
}
