如何使用 javascript 编辑结帐页面？

Question

I am trying to make the checkout page a change fields when a radio button is selected. So I have 2 options on the radio buttons option A and B When A is selected I want 2 fields below to remain available and other 2 to disappear. The other way around when the second radio button is checked.

I mostly used Wordpress for this website but I need a bit of code for this functionality.

function yesnoCheck('radio-5984531736') {
    if (this.radio-5984531736 == "Persoana fizica") {
        alert("check");
        document.getElementByClassName("juridica").style.display = "block";
    } else {
        document.getElementByClassName("fizica").style.display = "none";
    }
}

I have this code as script in the header. I am not sure if it is not correct or I don t have a code to call this function. The Id and class names are the following:

Radio buttons id: radio-5984531736 Info that should show when A selected class name: fizica Info that should show when A selected class name: juridical

I've made a demo similar to your task:

 function yesnoCheck() { var value = document.querySelector("[name='radio-5984531736']:checked").value; if (value === "v1") { document.querySelector(".fizica").style.display = "block"; document.querySelector(".juridica").style.display = "none"; } else { document.querySelector(".fizica").style.display = "none"; document.querySelector(".juridica").style.display = "block"; } } var form = document.querySelector("#formId"); form.addEventListener("change", yesnoCheck);

 <div> <form id="formId"> <div> <input type="radio" name="radio-5984531736" value="v1" id="v1id"> <label for="v1id">Persona fizica</label> <input type="radio" name="radio-5984531736" value="v2" id="v2id"> <label for="v2id">Persona juridica</label> </div> <div class="fizica"> Prenume <input name="prenume"><br/> Nume companie <input name="numecom"> </div> <div class="juridica"> Nume <input name="nume"><br/> CUI <input name="cui"> </form> </div>

Though I think it can be simpler in your case. Eg try writing this['radio-5984531736'] instead of this.radio-5984531736 . Also, you don't need 'radio-5984531736' in function yesnoCheck() {... .
