Error when using v-for in IE10 #7946

parapada73 · 2018-04-02T11:40:10Z

Version

2.5.16 / 2.5.17

Reproduction link

https://jsfiddle.net/plasmaeng/ndmjjkho/1/

Steps to reproduce

Running the code below in IE10 will result in the following error:

<!DOCTYPE html>
<html>
<head>
	<meta charset="utf-8">
	<meta http-equiv="X-UA-Compatible" content="IE=edge">
	<title>Page Title</title>
	<meta name="viewport" content="width=device-width, initial-scale=1">
	<script src="vue.js"></script>
</head>
<body>
<div id="app_test">
	<form>
	<select>
		<option v-for="value in L">{{value}}</option>
	</select>
	</form>
</div>

<script>
	var appTest = new Vue({
	el: '#app_test',
		data: {
			L : [ '1', '2' ,'3']
		}
	});
</script>
</body>
</html>

Here is the error message from IE10.

[Vue warn]: Error compiling template:

<div id="app_test">
	<form>
	<select>
		<option v-for="value in L">{{value}}</option>
	</select>
	</form>
</div>

invalid expression: Syntax error in  Raw expression: v-for="value in L"
invalid v-for alias "" in expression: v-for="value in L"

What is expected?

<option> is generated from 1 to 3.

What is actually happening?

<option> is not generated with error !!!

I have persuaded a senior for a long time to introduce Vue.js.
If this problem is solved, we plan to reorganize the site into Vue.js.
Please solve the problem.

The text was updated successfully, but these errors were encountered:

Confirm.

I insert:
console.log(render)
before line:
vnode = render.call(vm._renderProxy, vm.$createElement);

Generated render function in chrome, for example:
with(this){return _c('div',{attrs:{"id":"app_test"}},[_c('form',[_c('select',_l((l),function(value){return _c('option',[_v(_s(value))])}))])])}

In ie 10:
with(this){return _c('div',{attrs:{"id":"app_test"}},[_c('form',[_c('select',[_c('option',[_v(_s(value))])],2)])])}

P.S. With vue 2.5.15 no problem.

schoonc · 2018-04-03T10:27:31Z

If in vue 2.5.16 revert this commit (71b4b25) then problem disappears.

linkser · 2018-04-03T13:50:39Z

IE9 also has this problem

LinusBorg · 2018-04-03T13:58:30Z

probably the changes to the regex don'T work in <IE11 ?

schoonc · 2018-04-03T14:07:36Z

Yes.

    console.clear()
    var forAliasRE = /([^]*?)\s+(?:in|of)\s+([^]*)/;
    console.log('value in list'.match(forAliasRE))

Output in chrome:

["value in list", "value", "list"]

Output in ie10:

[" in list", "", ""]

May be replace [^] on [\s\S] ?

maetteam · 2018-04-05T23:51:27Z

Hallo, yeah that should fix the problem.
'\s' <=IE8 doesn't include all white spaces, non-breaking space (\xA0) and thin space (\x2009) are not included, if you are planning to run it on IE8 and below ;).

LinusBorg · 2018-04-06T07:52:55Z

VUe doesn't support <IE9.

pbelyaev · 2018-04-18T04:28:50Z

Any updates?

Closes vuejs#7946

huanghui8030 · 2018-04-19T03:29:42Z

Update vue version to v2.5.16 or v2.5.15, but error reporting. Don't know why?

resolved, Thanks!

weijuer · 2018-05-04T05:03:18Z

What can I do, if I need to use it in ie9+? Wait for next release version or change to 2.5.15?

LinusBorg · 2018-05-04T11:35:16Z

Right now, those are your two options, yes.

symmetriq · 2018-05-31T23:28:53Z

If you need one of the other fixes in 2.5.16, you can also just patch it yourself.

Search: /([^]*?)\s+(?:in|of)\s+([^]*)/
Replace: /([\s\S]*?)\s+(?:in|of)\s+([\s\S]*)/

This worked for me, but I decided to revert to 2.5.15 anyway (don't need any of the other changes in 2.5.16).

ufozy · 2018-08-15T01:59:37Z

use “version 2.4.2” is ok

murilobd · 2018-09-17T11:15:43Z

I'm on version 2.5.7 and still getting this issue with damn IE

TheWebTech · 2018-09-25T14:56:27Z

to anyone still experiencing this issue. @symmetriq's tip #7946 (comment)

was spot on, reverting to 2.5.15 solves it. I'd assume he's also correct on the regex adjustment.

tfnigel · 2018-10-03T04:47:01Z

Using 2.5.15, fixed it for me; I was seeing the problem on 2.5.17 on IE9.

alanwei43 · 2018-10-16T09:50:45Z

Vue@2.5.15 is ok

Closes #7946

mrquokka · 2018-11-15T10:38:23Z

Vue@2.5.15 is ok

2.5.17 have some error on IE9

  css_allowed_styles = {
    'default': '',
    'darkness': 'dark_theme.css'
```}

` v-for="(file_name, item) in css_allowed_styles" :value="item" :key="item">`

qinshenxue · 2018-11-30T06:58:44Z

the problem disappears in vue@2.5.17 when using ie9

mrquokka · 2018-12-01T07:06:35Z
