Basic usage
The prompt box in the Bootstrap framework has a very simple structure and is often used. Create a button
1. Define the prompt information through the value of the title attribute (you can also use the custom attribute src-title to set the prompt information) , the title attribute has a high priority
2. Use the data-placement custom attribute to control the position of the prompt information box. According to four different positions, data-placement has four values: top, right, bottom and left, respectively indicating that the prompt box appears at the top, right, bottom and left
3. There is also the most important parameter that is indispensable, data-toggle="tooltip"
[Triggering method]
The triggering method of the prompt box in the Bootstrap framework is slightly different from the plug-in introduced earlier. It cannot be triggered directly through the custom attribute data-. Must rely on JavaScript code triggering
The simplest triggering method is as follows:
$(function(){
$('[data-toggle="tooltip"]').tooltip();
});
<script>
$(function(){
$(&#39;[data-toggle="tooltip"]&#39;).tooltip();
});
</script>
##Attribute parameters
The prompt box component provides 7 custom attribute parameters for setting the prompt box
<script>
$(function(){
$(&#39;[data-toggle="tooltip"]&#39;).tooltip();
});
</script>
JS trigger
In addition to the simplest trigger method mentioned above, you can also specify an element separately, call the Tooltip component on the element, and provide various custom parameters in the form of javascript. There is no need to use element custom attributes starting with data-$(element).tooltip(options);
<button type="button" class="btn btn-default" data-toggle="tooltip" >按钮</button>
<script>
$(function(){
$('[data-toggle="tooltip"]').tooltip({
title:"我是提示语",
placement:'right'
});
});
</script>
[Keywords]
In addition to using the options object, you can also use keywords, 'show', 'hide', 'toggle', 'destroy'<body style="margin-top:50px;">
<button type="button" class="btn btn-default" data-toggle="tooltip" title="提示信息" id="btn1">按钮1</button>
<button type="button" class="btn btn-default" data-toggle="tooltip" title="提示信息" id="btn2">按钮2</button>
<button type="button" class="btn btn-default" data-toggle="tooltip" title="提示信息" id="btn3">按钮3</button>
<button type="button" class="btn btn-default" data-toggle="tooltip" title="提示信息" id="btn4">按钮4</button>
<script>
$(function(){
$('#btn1').tooltip('show');//显示提示语
$('#btn2').tooltip('hide');//关闭提示语
$('#btn3').tooltip('toggle');//反转提示语
$('#btn4').tooltip('destroy');//隐藏并销毁提示语
});
</script>
</body>
