Test IE browser compatibility with JavaScript's AngularJS_AngularJS
Short version
To ensure that Angular applications can work on IE please confirm:
1. Polyfill JSON.stringify on IE7 or earlier. You can use JSON2 or JSON3 for polyfills.
<!doctype html>
<html xmlns:ng="http://angularjs.org">
<head>
<!--[if lte IE 7]>
<script src="/path/to/json2.js"></script>
<![endif]-->
</head>
<body>
...
</body>
</html>
2. Add id="ng-app" to the root element at the connection point and use the ng-app attribute
<!doctype html> <html xmlns:ng="http://angularjs.org" id="ng-app" ng-app="optionalModuleName"> ... </html>
3. You cannot use custom element tags like 4. If you must use custom element tags, then you must take the following steps to ensure that IE8 and earlier versions can be used: 5. Use ng-style tag instead of style="{{ someCss }}". Subsequent versions will work under Chrome and Firefox but not IE versions <= 11 (the latest version at the time of writing). Version information IE has a lot of problems with non-standard tag elements. These problems can be divided into two broad categories, each with its own solutions. The good news is that these restrictions only apply to element tag names and not to element attribute names. Therefore, no special processing is required in IE: If you use HTML’s unknown tag mytag (the results of my:tag or my-tag are the same): should parse the following DOM: The expected behavior is that the BODY element has a mytag child element with some text. But this is not the case in IE (if the above revision is not included) In IE, the BODY element has three child elements: 1, a self-closing mytag. For example, the self-closing tag 2, a text node some text. In the above this should be a child element of mytag, not a sibling tag 3. A corrupted self-closing /mytag. This is a broken element because / characters are not allowed in element names. In addition, this sub-closed element is not part of the DOM, it is only used to describe the structure of the DOM. CSS style custom tag naming To ensure that CSS selectors can work on custom elements, the name of the custom element must be created in advance using document.createElement('my-tag'), regardless of the XML namespace.
<!doctype html>
<html xmlns:ng="http://angularjs.org" id="ng-app" ng-app="optionalModuleName">
<head>
<!--[if lte IE 8]>
<script>
document.createElement('ng-include');
document.createElement('ng-pluralize');
document.createElement('ng-view');
// Optionally these for CSS
document.createElement('ng:include');
document.createElement('ng:pluralize');
document.createElement('ng:view');
</script>
<![endif]-->
</head>
<body>
...
</body>
</html>
The important part is:
Good news
What will happen if I don't?
<html>
<body>
<mytag>some text</mytag>
</body>
</html>
#document
+- HTML
+- BODY
+- mytag
+- #text: some text
#document
+- HTML
+- BODY
+- mytag
+- #text: some text
+- /mytag
. / is optional, but the
tag is not allowed to have child elements. The browser treats
some text as three sibling tags, while some text is not
child elements.
<html xmlns:ng="needed for ng: namespace">
<head>
<!--[if lte IE 8]>
<script>
// 需要确认ng-include被正常解析
document.createElement('ng-include');
// 需求启用CSS引用
document.createElement('ng:view');
</script>
<![endif]-->
<style>
ng\:view {
display: block;
border: 1px solid red;
}
ng-include {
display: block;
border: 1px solid blue;
}
</style>
</head>
<body>
<ng:view></ng:view>
<ng-include></ng-include>
...
</body>
