无效的调用对象IE 11 XML数组的长度（getElementsByTagName）

时间：2016-01-26 13:38:15

标签： javascript xml internet-explorer-11

我不确定我应该如何在IE中解决此无效的调用对象错误。似乎IE不允许我在其他函数中使用全局表情符号？

    var emoticon = new Array();
    var emote_page;
    var emote_pages;

    getPaginateEmoticons(1);

    function navigateEmoticons(page){
        var i = ((page - 1) * 37);
        var p_emotes = page * 37;
        var emotes_div = document.getElementById('emoticons');

        if(page == 1){
            document.getElementById('previous_emo_p').style.display = 'none';
            document.getElementById('next_emo_p').style.display = 'inline';
        }
        else if(page > 1 && page < emote_pages){
            document.getElementById('previous_emo_p').style.display = 'inline';
            document.getElementById('next_emo_p').style.display = 'inline';
        }
        else if(page == emote_pages){
            document.getElementById('previous_emo_p').style.display = 'inline';
            document.getElementById('next_emo_p').style.display = 'none';
        }
        emotes_div.innerHTML = '';
        while(i < p_emotes && i <= emoticon.length){
            i++;
            emotes_div.innerHTML = emotes_div.innerHTML.concat('<button class="emobutton" onclick="insertEmote(document.getElementById(' + i + ').alt);"><img id="' + i + '" alt=":' + 
            emoticon[i].textContent.split('\\').pop().split('/').pop().split('.').shift() + ':" src="' + emoticon[i].textContent + '"></button>');
        }
        emote_page = page;
    }

    function getPaginateEmoticons(page){
        var emotes_div = document.getElementById('emoticons');
        var emote_pages_sel = document.getElementById('emote_page');
        var i;

        function handler(){
            if(this.status == 200 && this.responseXML != null){
                emoticon = this.responseXML.getElementsByTagName('file');
                emote_pages = Math.floor(emoticon.length / 37);

                        emote_pages_sel.innerHTML = emote_pages_sel.innerHTML.concat('<option value="' + i + '" selected="selected">Page ' + i + '</option>');
                    else if(i <= emote_pages && i > 1)
                        emote_pages_sel.innerHTML = emote_pages_sel.innerHTML.concat('<option value="' + i + '">Page ' + i + '</option>');

                document.getElementById('loadingIcon').style.display = 'none';
            }
            else{
                // something went wrong
            }
        }

        var client = new XMLHttpRequest();
        client.onload = handler;
        client.open("GET", "resources/emo_catalog.xml");
        client.send();
    }

while(i < p_emotes && i <= emoticon.length){行发生无效的调用对象错误。任何帮助将不胜感激。

我不知道IE 11，但是较低版本不支持@Route("/{id}_apartments.html", name="neighborhood_detail"), requirements={"id"="[a-zA-Z0-9_]+"}) ，但需要写一些像var client = new XMLHttpRequest();这样的想法。 这可能是ActiveXObject问题。

1

可能的问题编号function getXmlHttp(){ var xmlhttp; try { xmlhttp = new ActiveXObject("Msxml2.XMLHTTP"); } catch (e) { try { xmlhttp = new ActiveXObject("Microsoft.XMLHTTP"); } catch (E) { xmlhttp = false; } } if (!xmlhttp && typeof XMLHttpRequest!='undefined') { xmlhttp = new XMLHttpRequest(); } return xmlhttp; }

IE 8说Object不支持此属性

此代码在IE8中接收xml文档。 

var emoticon = new Array();
var emote_page;
var emote_pages;
function getPaginateEmoticons(page){
var emotes_div = document.getElementById('emoticons');
var emote_pages_sel = document.getElementById('emote_page');
var i;
var xhttp = new XMLHttpRequest();
xhttp.onreadystatechange = function() {
if (xhttp.readyState == 4 && xhttp.status == 200) {
myFunction(xhttp);
}
};

xhttp.open("GET", "http://victoria.ru/a.xml", true);
xhttp.send();

function myFunction(xml) {
var xmlDoc = xml.responseXML; alert(xmlDoc);
emoticon = xmlDoc.getElementsByTagName("file")[0].childNodes[0].nodeValue;   

emote_pages = Math.floor(emoticon.length / 37);
emote_page = page;

for(i = 0; i < 37; i++){
/* ... HERE ALSO ERRORS */ 
/*
if(i == 1) emote_pages_sel.innerHTML = emote_pages_sel.innerHTML.concat('<option value="' + i + '" selected="selected">Page ' + i + '</option>');
else if(i <= emote_pages && i > 1) emote_pages_sel.innerHTML = emote_pages_sel.innerHTML.concat('<option value="' + i + '">Page ' + i + '</option>');  
emotes_div.innerHTML = emotes_div.innerHTML.concat('<button class="emobutton" onclick="insertEmote(document.getElementById(' + i + ').alt);"><img id="' + i + '" alt=":' + 
emoticon[i].textContent.split('\\').pop().split('/').pop().split('.').shift() + ':" src="' + emoticon[i].textContent + '"></button>');

我最终必须将内容放入一个字符串并将其存储在隐藏的分割元素中，然后每次迭代时我都必须将字符串转换回数组。有点失败了使用XML文件的整个目的:(
