How to set text color in Angular-Material?

问题

I want to set one word in a sentence to have md-primary color, and another word to have the accent color. I assumed something like this:

<div>
    Hello <span class="md-primary">friend</span>. 
    How are <span class="md-accent">you</span>?
</div>

But those classes work only for some specified components.

What's the way to do it?

回答1:

I was just able to do this using Angular Material 1.1.0.

You use the md-colors directive similar to how you would ng-class:

<span md-colors="{color:'primary'}">...</span>

The above code will color the text the primary color. The object that you pass to md-colors uses the key as the css property (i.e. 'color', 'background', etc) and the value as the theme and/or palette and/or hue you want to use.

回答2:

Angular Material's docs explicitly enumerate list of components, which you able to differentiate with md-theme attribute:

md-button
md-checkbox
md-progress-circular
md-progress-linear
md-radio-button
md-slider
md-switch
md-tabs
md-text-float
md-toolbar

From Angular Material documentation, under Theming / Declarative Syntax.

So I think the short answer is: you can't do it.

TitForTat's comment has better solution https://github.com/angular/material/issues/1269#issuecomment-121303016

I created a module:

(function () {
        "use strict";
        angular
            .module('custiom.material', ['material.core'])
            .directive('cMdThemeFg', ["$mdTheming", function ($mdTheming) {
                return {
                    restrict: 'A',
                    link: postLink
                };
                function postLink(scope, element, attr) {
                    $mdTheming(element);
                    element.addClass('c-md-fg');
                }

            }])
            .directive('cMdThemeBg', ["$mdTheming", function ($mdTheming) {
                return {
                    restrict: 'A',
                    link: postLink
                };
                function postLink(scope, element, attr) {
                    $mdTheming(element);
                    element.addClass('c-md-bg');
                }
            }]);
    })();

and then append

.c-md-fg.md-THEME_NAME-theme.md-primary {    color: '{{primary-color}}'; }
.c-md-fg.md-THEME_NAME-theme.md-accent {    color: '{{accent-color}}'; } 
.c-md-fg.md-THEME_NAME-theme.md-warn {    color: '{{warn-color}}'; } 
.c-md-bg.md-THEME_NAME-theme.md-primary {    background-color: '{{primary-color}}'; } 
.c-md-bg.md-THEME_NAME-theme.md-accent {    background-color: '{{accent-color}}'; } 
.c-md-bg.md-THEME_NAME-theme.md-warn {    background-color: '{{warn-color}}'; }

into angular-material.js at 13783 line

angular.module("material.core").constant("......  HERE")

Then, I can simply apply c-md-theme-fg and/or c-md-theme-bg to element to apply theme colors. Like this:

<div c-md-theme-bg class="md-primary md-hue-3">dasdasdasd</div>
<span c-md-theme-bg class="md-primary">test</span>

It works.

I think the only way is to create your own custom palette as demonstrated in the docs: https://material.angularjs.org/latest/#/Theming/03_configuring_a_theme under the paragraph Defining Custom Palette. There you can define 'contrastDefaultColor' to be light or dark. If I am correct, that should do it.

However, I want to use a standard palette and override the text color to light, not define a whole new palette.

You can also (and I would suggest this) extend an existing palette with 'extendPalette'. This way you wouldn't have to define all hue's but only set the 'contrastDefaultColor' accordingly.

*edit: just tested a solution

Add this to your config function (look for angular code example on link provided above about configuring theme)

var podsharkOrange;

podsharkOrange = $mdThemingProvider.extendPalette('orange', {
  '600': '#689F38',
  'contrastDefaultColor': 'light'
});

$mdThemingProvider.definePalette('podsharkOrange', podsharkOrange);

$mdThemingProvider.theme('default').primaryPalette('podsharkOrange', {
  'default': '600'
});

I just set the 600 HUE to a green color to verify if the theme change works, so you can ignore that line in the extendPalette.

So this only changed the colour to light, not a specific colour. So it didn't answer your question, but might still come in handy.

The latests bits bring good news to this issue... This functionality has been added to the 1.1.0-rc3 (2016-04-13) version. It's not stable yet, but my first test on it are satisfactory.

Now you can use the mdColors directive and $mdColors service in conjunction with themes to achieve what you're looking for.

Please, take a look at:

https://github.com/angular/material/blob/master/CHANGELOG.md#110-rc3-2016-04-13

to see the announcement, and look for the mdColor directive and $mdColor service in the docs for some examples.

there is an issue in github that disccused this, like mentioned above TitForTat's comment in that issue almost had the perfect solution, but it doesn't work with costume palettes, i add a comment there with a fixed solution, you can check it out: https://github.com/angular/material/issues/1269#issuecomment-124859026

回答7:

Anchor element () is reacting to the Angular Material current theme setting since version 1.0.0-rc1: https://github.com/angular/material/blob/master/CHANGELOG.md#110-rc1-2016-03-09.

This answer is outdated please check @factalspawn answer

With 'pure' angular-material you can't. But you can try usign this: https://gist.github.com/senthilprabhut/dd2147ebabc89bf223e7

回答9:

For me i assume everything that starts with md- you can only apply theme colors to them.

In the documentation there are some components that are not documented where you can use theme colors. Example:

<md-subheader class="md-warn"> my subheader </md-subheader>
<md-icon class="md-accent"> </md-icon>
