javascript - 对象在 IE8 javascript 中不支持此属性或方法

Question

一切都可以在现代浏览器中完美运行，但对于 ie8，我收到此行的错误:

tabValues.push(tabParams[i].split(attribute_anchor_separator));

这里是整个函数:

function checkUrl()
{
  if (original_url != window.location || first_url_check)
  {
    first_url_check = false;
    url = window.location + '';
    // if we need to load a specific combination
    if (url.indexOf('#/') != -1)
    {
        // get the params to fill from a "normal" url
        params = url.substring(url.indexOf('#') + 1, url.length);
        tabParams = params.split('/');
        tabValues = [];
        if (tabParams[0] == '')
            tabParams.shift();
        for (var i in tabParams)
            tabValues.push(tabParams[i].split(attribute_anchor_separator));
        product_id = $('#product_page_product_id').val();
        // fill html with values
        $('.color_pick').removeClass('selected');
        $('.color_pick').parent().parent().children().removeClass('selected');
        count = 0;
        for (var z in tabValues)
            for (var a in attributesCombinations)
                if (attributesCombinations[a]['group'] === decodeURIComponent(tabValues[z][0])
                    && attributesCombinations[a]['attribute'] === tabValues[z][1])
                {
                    count++;
                    // add class 'selected' to the selected color
                    $('#color_' + attributesCombinations[a]['id_attribute']).addClass('selected');
                    $('#color_' + attributesCombinations[a]['id_attribute']).parent().addClass('selected');
                    $('input:radio[value=' + attributesCombinations[a]['id_attribute'] + ']').attr('checked', true);
                    $('input[type=hidden][name=group_' + attributesCombinations[a]['id_attribute_group'] + ']').val(attributesCombinations[a]['id_attribute']);
                    $('select[name=group_' + attributesCombinations[a]['id_attribute_group'] + ']').val(attributesCombinations[a]['id_attribute']);
                }
        // find combination
        if (count >= 0)
        {
            findCombination(false);
            original_url = url;
            return true;
        }
        // no combination found = removing attributes from url
        else
            window.location = url.substring(0, url.indexOf('#'));
    }
}
return false;
}

有什么想法吗？谢谢!

我注意到您在数组上使用 for..in ，但是使用 for..in 旨在用于对象(而不是数组)的迭代:

for ( var prop in obj1 ) {
    if ( obj1.hasOwnProperty(prop) ) {
        // loop body goes here
    }
}
