javascript - 在每个图块 javascript 中生成不同的文本
问题描述
我有包含姓名和姓氏的字符串数组。我创建了由随机名称和随机姓氏组成的用户名，我想在每个生成的图块中显示不同的用户名。我试图拆分姓名和姓氏，然后添加它做数组并获取随机数组索引，但它没有用。更好的解决方案是使用我的“用户名”。最大的问题是我无法修改我的 getData() 函数——它总是为每个图块分配相同的用户名。
function createGrid(x, y) {
for (var cols = 0; cols < x; cols++) {
for (var rows = 0; rows < y; rows++) {
console.log(namesArr)
console.log(x*y)
numberOfTiles = x*y;
var randonIndex = Math.floor(Math.random() * numberOfTiles);
// $(".usernameSpace").html(namesArr[randomIndex]);
//Doesn't work here
$('#container').append("<div class='grid'><div class = 'usernameSpace'></div></div>");
};
};
$('.grid').width(800 / x);
$('.grid').height(800 / x);
};
function refreshGrid() {
var x = $("#colsNumber")[0].value;
var y = $("#rowsNumber")[0].value;
$('.grid').remove();
createGrid(x, y);
};
function getData(count) {
var names = ["Michal ", "Jan ", "Katarzyna ", "Andrzej ", "Jozef ", "Bartek ", "Mikolaj ", "Tomasz ", "Julian ", "Brajan ", "Dzesika "];
var surnames = ["Noga ", "Kowalski ", "Nowak ", "Pazura ", "Duda ", "Komorowski ", "Tomczyk ", "Jozefowicz ", "Lechicki ", "Goldberg "];
result = [];
for (var i = 0; i < count; i++) {
var randomNameIndex = Math.floor(Math.random() * names.length);
var randomSurnameIndex = Math.floor(Math.random() * surnames.length);
var name = names[randomNameIndex];
var surname = surnames[randomSurnameIndex];
result.push({
name: name,
surname: surname
});
}
return result
}
function textDisplay() {
var numberOfTiles = 12;
//for (i = 0; i <= numberOfTiles; i++) {
var data = getData(12);

当你这样做时，在你的代码中：
$(".usernameSpace").html(namesArr[2]);
您正在将该类的所有标题分配给相同的 HTML 值。而是遍历您的标题并根据您的data变量为其分配一个值：
$(".usernameSpace").each(function(idx){
$(this).html(data[idx].surname);
});
尽管我建议在创建元素时将名称直接存储在元素的data属性中.usernameSpace。然后，您可以$(this).data("surname")在迭代元素时使用。data在元素数量不同的情况下，这种方式也会更安全，.usernameSpace同时也会使代码更简单。
function createGrid(x, y) {
for (var cols = 0; cols < x; cols++) {
for (var rows = 0; rows < y; rows++) {
console.log(namesArr)
console.log(x*y)
numberOfTiles = x*y;
var randonIndex = Math.floor(Math.random() * numberOfTiles);
// $(".usernameSpace").html(namesArr[randomIndex]);
//Doesn't work here
$('#container').append("<div class='grid'><div class = 'usernameSpace'></div></div>");
};
};
$('.grid').width(800 / x);
$('.grid').height(800 / x);
};
function refreshGrid() {
var x = $("#colsNumber")[0].value;
var y = $("#rowsNumber")[0].value;
$('.grid').remove();
createGrid(x, y);
};
function getData(count) {

var surname = surnames[randomSurnameIndex];
result.push({
