I'm making a plug-in where I can shorten the title of each entry in a forum index if it is too long. However, that is much harder than I expected.
Everything goes fine except when I get to the part where you actually have to print the items onto the DOM.
I get this error:
Uncaught TypeError: undefined is not a function
Here is my code with a bunch of notes I left to show you how it works.
var minimize = function() {
$('.segment').each(function(){
var title_box = $(this).children('.title');
// Selects the container of the title.
var title = $(this).children('.title').text().trim();
// Takes the child title of the each .segment class and selects its innards.
console.log(title);
var res = title.split("");
// Splits the text into an array.
console.log(res);
var fragment = [];
// initializing the empty array
for (x = 0; x < 4; x++) {
fragment.push(res[x]);
console.log(fragment);
// Loops through to make sure it's not more than 5 characters long
};
var final = fragment.join("");
// Joins the broken up string together.
title_box.empty();
final.appendTo(title_box);
});
};
What do you think I did wrong? And if there's any other ways for me to make this code more efficient, then please don't hesitate to tell me.
Right here you define fragment as an array:
var fragment = [];
You then populate it and do this:
var final = fragment.join("");
Read the docs on array.join to understand what that function does. In short, it joins your array together into a string
So now when you do this:
final.appendTo(title_box);
You get your TypeError because string doesn't have an appendTo method
What you probably wanted was a jquery object to call appendTo on.
Perhaps you meant:
title_box.text(final);
