Changing font-family on JS : can't set property of undefined












0















I seem to have a problem when trying to change font on click of a button with JS. Here is the function:



    var fontFamily = 'papyrus'

function changeFont(fontFamily){

    document.getElementsByClassName(".forma, .descrip").style.fontFamily 

        };


Here is my html line for the button that I use:



<input type="button" value="Mode Psychédélique" 

       onclick="chBackcolor('magenta'), changeColor('blue'), 

       changeHeadingColor('green'), changefont('papyrus')">      `


I get the error "Cannot set property of undefined", but I don't understand why since I put the variable.
Any thoughts?



BIG EDIT (sorry for that, former commenters)






javascript button onclick undefined fontfamily

  • Do the other 3 methods work for you (those which change color)? If you changed oDomElement to ele and your code still doesn't work, please edit your post accordingly. Why you calc matches and don't use it? More importantly, have you tried changing font for h2 – the elements for which you changed color successfully?

First, it seems like in your code



ele.style.fontFamily = papyrus



  1. No argument for papyrus


Unless you forgot to add "" quotes, there is no declared variable for papyrus




  1. Add type of font


This includes cursive, sans-serif, etc.
Try using this link if it helps: W3Schools fontFamily JS attribute

    You should avoid to like against w3school, they used to have many errors and inaccuracies. While they got better after many complains they still have many flaws and incomplete informations mdn font-family is a more complete reference.

Monofisismo

Image
Monofisismo (do grego: monos - "único, singular" e physis - "natureza") é o ponto de vista cristológico que defende que, depois da união do divino e do humano na encarnação histórica, Jesus Cristo, como encarnação do Filho ou Verbo ( Logos ) de Deus, teria apenas uma única "natureza", a divina, e não uma síntese de ambas. O monofisismo é contraposto pelo diofisismo (ou "diafisismo"), que defende que Jesus preservou em si as duas naturezas. Historicamente, o monofisismo se refere primordialmente à posição dos que (especialmente no Egito e, em menor grau, na Síria) rejeitaram as decisões do Concílio de Calcedônia em 451 (o quarto concílio ecumênico). Os membros mais moderados entre eles, porém, defendem a teologia "miafisita", que se tornou a oficial para as Igrejas Ortodoxas Orientais. Muitos ortodoxos orientais, porém, rejeitam essa classificação, mesmo como um termo genérico, mas ele é amplamente utilizado na literatura históri

Olmecas

Monumento 1, uma das quatro cabeças colossais encontradas em La Venta, com altura aproximada de 3 metros Olmecas é a designação do povo e da civilização que estiveram na origem da antiga cultura pré-colombiana da Mesoamérica e que se desenvolveram nas regiões tropicais do centro-sul do atual México durante o pré-clássico, próximo de onde hoje estão localizados os estados mexicanos de Veracruz e Tabasco, no Istmo de Tehuantepec, numa zona designada área nuclear olmeca. A cultura olmeca floresceu nesta região aproximadamente entre 1500 e 400 a.C., [ 1 ] e crê-se que tenha sido a civilização-mãe de todas as civilizações mesoamericanas que se desenvolveram posteriormente. [ 2 ] No entanto, desconhece-se a sua exacta filiação étnica, ainda que existam numerosas hipóteses colocadas para tentar resolver esta questão. O etnónimo olmeca foi cunhado pelos arqueólogos do século XX, e não devem confundir-se com os muito posteriores olmecas-xicalancas que ocuparam vários locais do México
