Javascript IE8淘汰3.3.0错误

我不确定是什么原因导致了它，但IE8指出这段代码中的catch行导致了一个错误，导致页面无法加载。我真的不知道是什么引起的。我甚至将所有保留的关键字都用引号括起来，以避免在淘汰中出现冲突

ko.utils.arrayForEach(orderedBindings, function(bindingKeyAndHandler) {
    // Note that topologicalSortBindings has already filtered out any nonexistent binding handlers,
    // so bindingKeyAndHandler.handler will always be nonnull.
    var handlerInitFn = bindingKeyAndHandler.handler["init"],
        handlerUpdateFn = bindingKeyAndHandler.handler["update"],
        bindingKey = bindingKeyAndHandler.key;

    if (node.nodeType === 8) {
        validateThatBindingIsAllowedForVirtualElements(bindingKey);
    }

    try {
        // Run init, ignoring any dependencies
        if (typeof handlerInitFn == "function") {
            ko.dependencyDetection.ignore(function() {
                var initResult = handlerInitFn(node, getValueAccessor(bindingKey), allBindings, bindingContext['$data'], bindingContext);

                // If this binding handler claims to control descendant bindings, make a note of this
                if (initResult && initResult['controlsDescendantBindings']) {
                    if (bindingHandlerThatControlsDescendantBindings !== undefined)
                        throw new Error("Multiple bindings (" + bindingHandlerThatControlsDescendantBindings + " and " + bindingKey + ") are trying to control descendant bindings of the same element. You cannot use these bindings together on the same element.");
                    bindingHandlerThatControlsDescendantBindings = bindingKey;
                }
            });
        }

        // Run update in its own computed wrapper
        if (typeof handlerUpdateFn == "function") {
            ko.dependentObservable(
                function() {
                    handlerUpdateFn(node, getValueAccessor(bindingKey), allBindings, bindingContext['$data'], bindingContext);
                },
                null,
                { disposeWhenNodeIsRemoved: node }
            );
        }
    } catch (ex) {
        ex.message = "Unable to process binding \"" + bindingKey + ": " + bindings[bindingKey] + "\"\nMessage: " + ex.message;
        throw ex;
    }
});

如果您在项目中使用了Knockout.js，那么在某些时候您可能会遇到以下错误“uncaughtreferenceerror:无法处理绑定”。最可能的原因是某处输入错误或忘记更改上下文。。例如，您在foreach绑定中，忘记使用$parent

这可能会导致进一步的innerHtml错误，从而阻止页面加载js。

引发/显示的实际错误是什么？您可以共享更多代码吗？你的装订是什么样子的？错误是怎么说的？@dperry

对象不支持此属性或方法

@RPNiemeyer我正在调试一个非常古老的东西，有太多东西无法精确地说明它的来源。嗯，无意冒犯，但是如果你不能将它缩小到一个尽可能小的复制，您希望我们如何帮助您？出现故障的绑定是什么样子的？
