显示和隐藏一个问题的文本功能。 如何删除最初的“少展示”元素？

Question

The code functions the way that it should.

I am having a hard time figuring out how to initially hide the "show less" button from the display.

All i'm doing here is grabbing the first paragraph and hiding the rest to show once the continue reading button is clicked. However the show less button is on the display initially. I would like to figure out how to remove it. I tried taking it away in the.html method but then it never shows up at all.

Any suggestions?

 jQuery(function() { //Read more / read less text functionality. Add "minimize" to any paragraph of text. var wrapPara = jQuery('.minimize p').nextAll().wrapAll('<div class="hide-body">'); var minimized_elements = jQuery('.minimize > p:first-child'); var continueReading = '<a href="#" class="btn btn-success mr-3 more">Continue reading</a>'; var showLess = '<a href="#" class="btn btn-success less">Show less</a>'; minimized_elements.each(function() { jQuery(this).html( minimized_elements.text() + '<span>... </span>' + continueReading + " " + showLess ).appendTo(".minimize"); }); jQuery('a.more', minimized_elements).click(function(event) { event.preventDefault(); jQuery(this).toggle(); jQuery(this).next().show(); jQuery(".hide-body").show(); }); jQuery('a.less', minimized_elements).click(function(event) { event.preventDefault(); jQuery(this).toggle(); jQuery(this).prev().show().prev().show(); jQuery(".hide-body").hide(); jQuery(".less").show(); }); });

 .hide-body { display: none; }

You want Show less link initially hidden, so just add style="display:none;" in its html like below.

var showLess = '<a href="#" class="btn btn-success less" style="display:none;">Show less</a>';

Moreover I think once user expands the paragraph and then click on Show less it should hide that link. So I've commented jQuery(".less").show(); line.

Complete code is below. You can test it.

 jQuery(function() { //Read more / read less text functionality. Add "minimize" to any paragraph of text. var wrapPara = jQuery('.minimize p').nextAll().wrapAll('<div class="hide-body">'); var minimized_elements = jQuery('.minimize > p:first-child'); var continueReading = '<a href="#" class="btn btn-success mr-3 more">Continue reading</a>'; var showLess = '<a href="#" class="btn btn-success less" style="display:none;">Show less</a>'; minimized_elements.each(function() { jQuery(this).html( minimized_elements.text() + '<span>... </span>' + continueReading + " " + showLess ).appendTo(".minimize"); }); jQuery('a.more', minimized_elements).click(function(event) { event.preventDefault(); jQuery(this).toggle(); jQuery(this).next().show(); jQuery(".hide-body").show(); }); jQuery('a.less', minimized_elements).click(function(event) { event.preventDefault(); jQuery(this).toggle(); jQuery(this).prev().show().prev().show(); jQuery(".hide-body").hide(); // jQuery(".less").show(); // Commented to hide show less link once it clicked. }); });

 .hide-body { display: none; }
