单击阅读更多后如何在我的代码上添加阅读更少按钮？

Question

I need some help with my code.

So, I have a "read more" function, but I always have "Read more" text on that button, and I need to make "Read more" - "Read less" text, how can I add "Read less" text to my code, after click?

Here is my view:

<span class="small2" style="max-height: 120px"  class="col-md-6" align="justify" >{{ $review->review_message }}</span>

Here is my script:

$(".small2").each(function () {
    text = $(this).text();
    if (text.length > 200) {
        $(this).html(text.substr(0, 100) + '<span class="elipsis">' + text.substr(100) + '</span><a class="elipsis" href="#">Read more</a>' + 'salut');
    }

});
$(".small2 > a.elipsis").click(function (e) {
    e.preventDefault(); //prevent '#' from being added to the url
    $(this).prev('span.elipsis').fadeToggle(500);
});

Answer 1

Please try it:

$(".small2 > a.elipsis").click(function (e) {
    e.preventDefault(); //prevent '#' from being added to the url
    $(this).prev('span.elipsis').fadeToggle(500);

    if ( $(this).text() == "Read more" )
      $(this).text('Read less');
    else
      $(this).text('Read more');

});

I've made a snippet for your problem, look at it:

 var readMore = true; $(".small2").each(function () { text = $(this).text(); if (text.length > 200) { $(this).html(text.substr(0, 100) + '<span class="elipsis">' + text.substr(100) + '</span><a class="elipsis" href="#"> Read more</a>'); $('span.elipsis').fadeToggle(10); } }); $(".small2 > a.elipsis").click(function (e) { e.preventDefault(); //prevent '#' from being added to the url $('span.elipsis').fadeToggle(500); $('a.elipsis').text(readMore? 'Read less': 'Read more'); readMore =;readMore; });
