在寻找解决方案以从复选框的刻度中切换文本框时,我在StackOverflow中的另一篇文章中碰到了这个小提琴。

<h3 class="ui-widget-header ui-corner-all">Toggle</h3>
<p>
Etiam libero neque, luctus a, eleifend nec, semper at, lorem. Sed pede. Nulla lorem metus, adipiscing ut, luctus sed, hendrerit vitae, mi.

javascript + jquery
function runEffect() {
// get effect type from
var selectedEffect = 'slide';
// most effect types need no options passed by default
var options = {};
// some effects have required parameters
if ( selectedEffect === "scale" ) {
options = { percent: 0 };
} else if ( selectedEffect === "size" ) {
options = { to: { width: 200, height: 60 } };
}
// run the effect
$( "#effect" ).toggle( selectedEffect, options, 500 );
};
$( "#effect" ).toggle( false );
// set effect from select menu value
$("#run_effect").click(function(){
if($('#run_effect').is(':checked')){
runEffect();

该小提琴只能在jQuery 1.9.2上使用。我使用3.3.1、1.9.1进行了尝试,但无法正常工作。
所以,我的第一个问题是:那怎么样?
第二个问题是:如何使用3.3.1使其正常工作?
请记住,我不是前端开发人员,所以对我来说,所有这些都像“中文”。
答案 0 :(得分:1)
您需要包括jQuery以及jQuery UI的CSS和脚本。示例(请参见HTML顶部)
现在,关于为什么/如何使用jsFiddle,这是他们的设计决定,当选择1.9.1以外的其他版本作为jQuery版本时,不包括jQuer UI切换。
注意:可以回答您的问题。
现在我对此很感兴趣,并连接了您的选择/复选框,并添加了一个按钮,以在单击时显示所选的效果。使用条件创建对象并使用该对象,请随时在此处使用“答案”。它仍然会触发“更改”事件-通过单击按钮,如果未选中它就不会显示任何效果,只是在那里显示/隐藏基本jQuery。
function runEffect(pick, choice) {
// get effect type from
var selectedEffect = choice.val(); //'slide';
// console.log(selectedEffect);
let defaultOptions = {
duration: 500,
scale: {
options: {
percent: 0
}
},
size: {
options: {
to: {
width: 200,
height: 60
}
}
}
};
let options = defaultOptions[selectedEffect] ? (defaultOptions[selectedEffect].options ? defaultOptions[selectedEffect].options : {}) : {};
// run the effect IF checked?
if (pick) {
$("#effect").toggle(selectedEffect, options, defaultOptions.duration);
} else {
// just basic jquery hide/show toggle
$("#effect").toggle();
}
};
// this is an alias for and the same as $("#effect").hide();
$("#effect").toggle(false);
// set effect from select menu value
// this is better with '.on(' and should use "change" not click
$("#run_effect").on('change', function() {
let me = $(this).is(':checked');
let choice = $('#effectTypes');
runEffect(me, choice);
});
$("#show-effect").on('click', function() {
$("#run_effect").trigger('change');
});
