Installation

Install the npm package.

npm i ng2-tooltip-directive
    

Import Ng2Module:

import { TooltipModule } from 'ng2-tooltip-directive';
 
@NgModule({
    imports: [ TooltipModule ]
}) 

Usage

Options can be set in the directive tag, so they have the highest priority.

<span tooltip="Tooltip" placement="top" showDelay="500">Tooltip on top</span>

You may pass as an object:

<span tooltip="Tooltip" [options]="myOptions">Tooltip on left</span>

myOptions = {
    'placement': 'left',
    'showDelay': 500
}

You can pass HTML as content :

<span tooltip="<p>Hello i'm a <strong>bold</strong> text!</p>">
  Tooltip with HTML content
</span>

<ng-template #HtmlContent>
  <p>Hello i'm a <strong>bold</strong> text!</p>
</ng-template>

<span [tooltip]="HtmlContent" contentType="template">
  Tooltip with template content
</span>

Set default values

Create a file with your settings, for example:

import { TooltipOptions } from 'ng2-tooltip-directive';

export const MyDefaultTooltipOptions: TooltipOptions = {
  'show-delay': 500
}

And pass your parameters when importing the module:

import { TooltipModule, TooltipOptions } from 'ng2-tooltip-directive';
import { MyDefaultTooltipOptions } from './my-default-options';
 
@NgModule({
    imports: [ 
      TooltipModule.forRoot(MyDefaultTooltipOptions as TooltipOptions)
    ]
})
