javascript 以编程方式设置进度条宽度

Posted 2021-05-03

// Automate progress bar width based on length of fieldset in current_form

function progressWidths() {
    var questionCount = $('#' + current_form.form_id + ' fieldset').length;
    var eachWidth = 100 / questionCount;

    for (var i = 0; i < questionCount; i++) {

       $('#' + current_form.form_id +' .progress-bar')[i].style.width = [i + 1] * eachWidth + '%';
        console.log([i + 1] * eachWidth);
        
    }
}
