IE8 的兼容性问题总结

在IE8中,下面的代码报错:

$('#invoiceListDot').text(htmlTemplate);

 

说明:invoiceListDot 是一个script标签 

<script id="invoiceListDot" type="text/x-dot-template">
               {{? it.invoiceInfoDtos}}
               {{ for(var prop=0;prop
               <it.invoiceInfoDtos.length
                       ; prop++){ }}
                       {{? it.invoiceInfoDtos[prop]}}
               <div class="{{ if(prop==0 && it.create==true){}}invoice-infor {{ }else {}}no-invoice{{ }}}"
                    data-index="{{= prop }}">
                   <span class="no-ivoice-icon">span>
                   <span>普通发票span>
                   <span class="ivo-margin invoiceType">{{= it.invoiceInfoDtos[prop].content }}span>
                   <span class="ivo-margin invoiceCompany">{{= it.invoiceInfoDtos[prop].title }}span>
                   <span class="ivo-margin invoiceAddress">{{= it.invoiceInfoDtos[prop].address }}span>
                   <span class="ivo-margin invoicePerson">{{= it.invoiceInfoDtos[prop].receiver }}span>
                   <span class="ivo-margin invoicePhone">{{= it.invoiceInfoDtos[prop].phone }}span>
               div>
               {{?}}
               {{ } }}
               {{?}}
           script>

 改为如下代码也报错:

$('#invoiceListDot').html(htmlTemplate);

 

这是IE8的兼容性问题.

解决方法:

在js中判断浏览器类型,若是IE8,则执行

$('#invoiceListDot').innerHTML = htmlTemplate;

整个逻辑判断如下:

if (getBrowserVersion.isIE8) {
       $('#invoiceListDot').innerHTML = htmlTemplate;
   } else {
       $('#invoiceListDot').text(htmlTemplate);
   }

  

 

 获取script标签的内容的时候:

 

var tmplate = $invoiceListDot.text();//IE8中返回空字符串
                   if (!tmplate) {
                       console.log('$invoiceListDot.text() return null');
                       tmplate = $invoiceListDot.html();
                   }

 

 

 

new Date('2015-08-05 23:12:20')

在chrome中,下面的语法是正确的:

 但是在IE8中不支持,所以增加了判断:

if (typeof  window.willEndTime == 'string') {//IE中
        productInfo2.willEndTime = window.willEndTime;
    } else {
        productInfo2.willEndTime = new Date(window.willEndTime).format("yyyy-MM-dd");
    }

 

 那么如何判断浏览器是IE8呢?

 

/***
 * get browser type and browser version and language
 when page open,the function will be executed automaticly
 * @param write22
 * @returns {{systemLanguage,userLanguage,ver}}
 */
getBrowserVersion = (function (write22) {
    var browser = {};
//    console.dir(navigator);
    var userAgent = navigator.userAgent.toLowerCase();
    /*for(osvId in navigator){
     var value222=navigator[osvId];
     document.writeln(osvId+": "+value222+'');
     }*/
    var lang22 = navigator.language;
//    document.writeln(userAgent+'');
//    document.writeln(navigator.appCodeName+'');
    var s;
    (s = userAgent.match(/msie ([\d.]+)/)) ? browser.ie = s[1] : (s = userAgent.match(/firefox\/([\d.]+)/)) ? browser.firefox = s[1] : (s = userAgent.match(/chrome\/([\d.]+)/)) ? browser.chrome = s[1] :
        (s = userAgent.match(/opera.([\d.]+)/)) ? browser.opera = s[1] : (s = userAgent.match(/version\/([\d.]+).*safari/)) ? browser.safari = s[1] : 0;
    var version = "";
    if (browser.ie) {
        version = browser.ie;
        if (write22 && write22 != false && write22 != 'false') {
            document.writeln('IE');
        }
        if (!browser.lang || browser.lang == undefined) {
            lang22 = navigator.browserLanguage;
            browser.systemLanguage = navigator.systemLanguage;
            browser.userLanguage = navigator.userLanguage;
        }
    }
    else if (browser.firefox) {
        version = browser.firefox;
        browser.mozilla = browser.firefox;
        if (write22 && write22 != false && write22 != 'false') {
            document.writeln('firefox');
        }
    }
    else if (browser.chrome) {
        version = browser.chrome;
        if (write22 && write22 != false && write22 != 'false') {
            document.writeln('chrome');
        }
    }
    else if (browser.opera) {
        version = browser.opera;
        if (write22 && write22 != false && write22 != 'false') {
            document.writeln('opera');
        }
    }
    else if (browser.safari) {
        version = browser.safari;
        if (write22 && write22 != false && write22 != 'false') {
            document.writeln('Safari');
        }
    }
    else {
        version = 'unknown browser';
    }
    browser.ver = version;
    if (lang22 && lang22 != undefined) {
        browser.lang = lang22.toLowerCase();
    }
    browser.isIE8 = (browser.ie && (version === '8.0' || version === '8'));
    return browser;
})();

 上述脚本见附件

 使用方法:

f (getBrowserVersion.isIE8) {
        $('#invoiceListDot').innerHTML = htmlTemplate;
    } else {
        $('#invoiceListDot').text(htmlTemplate);
    }

 

 Ie识别不了有空格的json

 比如

{

"path":"huang wei"

}

 

IE7中动态创建表格时,必须要创建tbody,否则表格不显示

var tb = put('table.service');
if (BrowserVersion.isIE7 || BrowserVersion.isIE6) {
                tb=put(tb,'tbody');
             }
