blocks|key|2724021|text|您应该能够对条件执行&&操作：|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|2724022|ng-disabled="condition1+&&+condition2"|code-block|syntax|javascript|2724023|entityMap^0|A|2|0|0^^$0|@$1|2|3|4|5|6|7|M|8|@$9|N|A|O|B|C]]|D|@]|E|$]]|$1|F|3|G|5|H|7|P|8|@]|D|@]|E|$I|J]]|$1|K|3|-4|5|6|7|Q|8|@]|D|@]|E|$]]]|L|$]]

You should be able to <code>&amp;&amp;</code> the conditions:

<pre><code>ng-disabled="condition1 &amp;&amp; condition2"
</code></pre>

blocks|key|2514245|text|实际上，对我来说，ng-disabled指令与“%7C%7C”逻辑运算符一起工作。“&&”只计算一个条件。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|2514246|http://jsbin.com/kuqilejesi/2/edit?html,js,output|offset|length|2514247|entityMap|0|LINK|mutability|MUTABLE|url^0|0|0|1D|0|0^^$0|@$1|2|3|4|5|6|7|M|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|N|8|@]|9|@$D|O|E|P|1|Q]]|A|$]]|$1|F|3|-4|5|6|7|R|8|@]|9|@]|A|$]]]|G|$H|$5|I|J|K|A|$L|C]]]]

Actually the ng-disabled directive works with the " || " logical operator for me. The " &amp;&amp; " evaluate only one condition.

blocks|key|41340|text|旺尼是对的。&&运算符在HTML中不起作用。使用Angular时，必须在多个条件下使用双管道(%7C%7C)。|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|41341|entityMap^0|6|2|1B|2|0^^$0|@$1|2|3|4|5|6|7|H|8|@$9|I|A|J|B|C]|$9|K|A|L|B|C]]|D|@]|E|$]]|$1|F|3|-4|5|6|7|M|8|@]|D|@]|E|$]]]|G|$]]

Wanny is correct. The <code>&amp;&amp;</code> operator doesn't work in HTML. With Angular, you must use the double pipes (<code>||</code>)for multiple conditions.

blocks|key|41623|text|确保以正确的优先顺序包装条件|type|unstyled|depth|inlineStyleRanges|entityRanges|data|41624|ng-disabled="((!product.img)+%7C%7C+(!product.name))"|code-block|syntax|javascript|41625|entityMap^0|0|0^^$0|@$1|2|3|4|5|6|7|I|8|@]|9|@]|A|$]]|$1|B|3|C|5|D|7|J|8|@]|9|@]|A|$E|F]]|$1|G|3|-4|5|6|7|K|8|@]|9|@]|A|$]]]|H|$]]

Make sure you wrap the condition in the correct precedence

<pre><code>ng-disabled="((!product.img) || (!product.name))"
</code></pre>

blocks|key|41149|text|这种方式对我很管用|type|unstyled|depth|inlineStyleRanges|entityRanges|data|41150|ng-disabled="(user.Role.ID+!=+1)+&&+(user.Role.ID+!=+2)“|41151|entityMap^0|0|0^^$0|@$1|2|3|4|5|6|7|F|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|G|8|@]|9|@]|A|$]]|$1|D|3|-4|5|6|7|H|8|@]|9|@]|A|$]]]|E|$]]

this way worked for me

ng-disabled="(user.Role.ID != 1) &amp;&amp; (user.Role.ID != 2)"

blocks|key|41638|text|你可以试试这样的东西。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|41639|<button+class="button"+ng-disabled="(!data.var1+&&+!data.var2)+?+false+:+true">
</button>|code-block|syntax|javascript|41640|它对我来说工作得很好。|41641|entityMap^0|0|0|0^^$0|@$1|2|3|4|5|6|7|K|8|@]|9|@]|A|$]]|$1|B|3|C|5|D|7|L|8|@]|9|@]|A|$E|F]]|$1|G|3|H|5|6|7|M|8|@]|9|@]|A|$]]|$1|I|3|-4|5|6|7|N|8|@]|9|@]|A|$]]]|J|$]]

You can try something like this.

<pre><code>&lt;button class="button" ng-disabled="(!data.var1 &amp;&amp; !data.var2) ? false : true"&gt;
&lt;/button&gt;
</code></pre>

Its working fine for me.

blocks|key|2724244|text|要禁用按钮，两个变量都必须为false：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|2724245|<button+class="button"+ng-disabled="(!data.var1+&&+!data.var2)+?+false+:+true">
</button>|code-block|syntax|javascript|2724246|entityMap^0|0|0^^$0|@$1|2|3|4|5|6|7|I|8|@]|9|@]|A|$]]|$1|B|3|C|5|D|7|J|8|@]|9|@]|A|$E|F]]|$1|G|3|-4|5|6|7|K|8|@]|9|@]|A|$]]]|H|$]]

Both variable must be false for the button to be disabled:
<pre><code>&lt;button class=&quot;button&quot; ng-disabled=&quot;(!data.var1 &amp;&amp; !data.var2) ? false : true&quot;&gt;
&lt;/button&gt;
</code></pre>

I need to check that two conditions are both true before enabling a button:

Here is an example:

<pre><code>&lt;button type="submit" ng-disabled="frmUser.pw2.$error.pwMatch" class="btn btn-primary" ng-click="ChangePassword()"&gt;Change&lt;/button&gt;
</code></pre>

This example only contains one condition within <code>ng-disabled</code>. How would I add another such as a scope variable?

How do I add multiple conditions to "ng-disabled"?

在启用按钮之前，我需要检查是否有两个条件都为 true：下面是一个示例：<button type="submit" ng-disabled="frmUser.pw2.$error.pwMatch" class="btn btn-primary" ng-click="ChangePassword()">Change</b...
