问题
I'm using Angular JS v1.1.5, and found an interesting IE-related issue.
In IE 9, 10, 11 and Edge, the following does not seem to work, even though it works fine in Chrome:
<div style="width: {{progress.percent()}}%;"></div>
Whereas this works in all browsers:
<div ng-style="{width: progress.percent() + '%'}"></div>
I'm curious why the first option doesn't work in IE/Edge. Are there any known bugs around this?
回答1:
When IE 9 & 10 tries to render that HTML, it basically removes the invalid HTML found on HTML to be parse.
So having style="display: {{'block'}}" consider as invalid html, because it has unknown {{}} syntax & it make that attribute rendered as style=""
Other than having ng-style there you could use ng-attr-* directive like below
<div ng-attr-style="{{'width: '+ progress.percent() +'%;'}}"></div>
which will create style attribute when progress.percent() value does changed.
For more information look at this old logged github issue
