插件工具提示-中继标题

Question

I am using the plugin "tooltipster" but I would like to truncate the title to 30 characters and add hellips.

I have a list of 3 links. Below is the code and added a link to example

$('.tooltip').tooltipster({
    animation: 'fade',
    delay: 200,
    touchDevices: false,
    trigger: 'hover',
    position: 'bottom',
    theme: 'tooltipster-shadow'
});


$('.box a').each(function(){
    if ($(this).attr('title').text().length > 20) {
        $(this).attr('title').text($(this).text().substr(0, 17)); 
        $(this).attr('title').append(' ...');
    }

});

thank you very much!

Answer 1

1. You should execute your scripts after the dom is ready, use $(document).ready(function(){}) or $(function(){})
2. To get attribute value use $.attr('attribute') instead of $.attr('attribute').text()
3. To update the attribute value use $.attr('attribute', 'new value') instead of $.attr('attribute').text('new value')

Your new code will be like this:

$(function(){

    $('.box a').each(function(){
        var title = $(this).attr('title');
        if (title.length > 20) {
            $(this).attr('title', title.substr(0, 17) + '...'); 
        }
    })

    $('.tooltip').tooltipster({
        animation: 'fade',
        delay: 200,
        touchDevices: false,
        trigger: 'hover',
        position: 'bottom',
        theme: 'tooltipster-shadow'
    });

})
