Conditional without any triggering event

I have a code that currently works using the click or keyup function. However, I am looking for a way to make it work without relying on keyup or click events. Is there a way to automatically change the line-height when the page is loaded?

(Please note that the divs in question have varying heights and I already have a jQuery document ready function in place)

You can view the code in action on JSFiddle: http://jsfiddle.net/n32u4gnq/1/

$(".note").on("load",function(){
var noteHeight = $(this).height();

if (noteHeight == 25) {
$(this).css("line-height","25px");
} else {
$(this).css("line-height","normal");
}
});
#wrap { 
margin:0 auto;
max-width:420px;
}

.note {
width:100%;
min-height:25px; line-height:25px;
margin-bottom:5px;
padding:0px 10px;
text-align:left;
outline:none;
display:inline-block;
background:whiteSmoke;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div id="wrap" >
<div class="note" id="primer" contenteditable="true"> First line, First line, First line, First line, First line, First line, First line, First line, First line, First line, First line, First line, First line, First line, First line, First line,  </div>
<div class="note" contenteditable="true"> Second line </div>
</div>

Answer №1

$(document).ready(function(){
   $(".note").trigger('keyup');
});

To improve your code, consider separating the line-height function into a separate function called changeLineHeight. This way, you can trigger it with different events like keydown, keyup, etc., and also run it within doc.ready using changeLineHeight().

For example:

var changeLineHeight = function(){
    $(".notes").each(function(i,el){
        var noteHeight = $(this).height();
        if (noteHeight == 25) {
            $(this).css("line-height","25px");
        } else {    
            $(this).css("line-height","normal");
        }
    });
};
$(document).on('keyup keydown paste click', changeLineHeight)
.ready(function(){
    changeLineHeight();
});

Answer №2

To ensure your code only runs after the document is fully loaded, wrap it inside the $(document).ready() event. You can then use the .each() function to loop through each of your elements.

Since your CSS already specifies a line-height of 25px for your element, you can simply modify it if needed:

$(document).ready(function() {
    $('.note').each(function() {
        var noteHeight = $(this).height();

        if (noteHeight > 25)
            $(this).css("line-height", "normal");
    });
});

You can test this out on JSFiddle: http://jsfiddle.net/n32u4gnq/14/

Please give it a try and let me know if this solution works for you!

Answer №3

Make sure to enclose your code within $(document).ready() to ensure that the DOM is fully loaded before any manipulation occurs.

$(document).ready(function() {
 $(".note").each(function(){
   var noteHeight = $(this).height();

    if (noteHeight == 25) {
        $(this).css("line-height","25px");
    } else {    
        $(this).css("line-height","normal");
    }
  });
});

Answer №4

The issue stemmed from retrieving the height of the document instead of the specific element. Consider replacing your document listener with this revised code:

$(document).ready(function() {

    var mainElement = document.getElementById("mainElement");
    var elementHeight = mainElement.clientHeight;
    
    if (elementHeight == X) {
        $(mainElement).css("line-height","Ypx");
    } else {    
        $(mainElement).css("line-height","normal");
    }

});
