我正在创建 Filter Image Gallery 。默认情况下,当页面加载显示所有图像时。我有两个四个不同的标签

<强>1。全部显示 2.自然 3.汽车 4.人

现在我不想显示所有图像。默认情况下,我想在页面加载后默认显示 Nature 滤镜图像。

请检查我的代码:Code is here

另外,附上我的代码

   filterSelection("all")
function filterSelection(c) {
var x, i;
x = document.getElementsByClassName("column");
if (c == "all") c = "";
for (i = 0; i < x.length; i++) {
w3RemoveClass(x[i], "show");
if (x[i].className.indexOf(c) > -1) w3AddClass(x[i], "show");
}
}

function w3AddClass(element, name) {
var i, arr1, arr2;
arr1 = element.className.split(" ");
arr2 = name.split(" ");
for (i = 0; i < arr2.length; i++) {
if (arr1.indexOf(arr2[i]) == -1) {element.className += " " + arr2[i];}
}
}

function w3RemoveClass(element, name) {
var i, arr1, arr2;
arr1 = element.className.split(" ");
arr2 = name.split(" ");
for (i = 0; i < arr2.length; i++) {
while (arr1.indexOf(arr2[i]) > -1) {
arr1.splice(arr1.indexOf(arr2[i]), 1);
}
}
element.className = arr1.join(" ");
}

默认情况下如何更改性质我不想显示所有图像。我累了但仍然显示所有图像。提前谢谢

最佳答案

在js文件中修改这一行:

filterSelection("all")

通过

filterSelection("nature")

并删除勾选的“all”单选框并添加勾选的“nature”单选框

filterSelection("nature")
function filterSelection(c) {
var x, i;
x = document.getElementsByClassName("column");
if (c == "all") c = "";
for (i = 0; i < x.length; i++) {
w3RemoveClass(x[i], "show");
if (x[i].className.indexOf(c) > -1) w3AddClass(x[i], "show");
}
}

function w3AddClass(element, name) {
var i, arr1, arr2;
arr1 = element.className.split(" ");
arr2 = name.split(" ");
for (i = 0; i < arr2.length; i++) {
if (arr1.indexOf(arr2[i]) == -1) {element.className += " " + arr2[i];}
}
}

function w3RemoveClass(element, name) {
var i, arr1, arr2;
arr1 = element.className.split(" ");
arr2 = name.split(" ");
for (i = 0; i < arr2.length; i++) {
while (arr1.indexOf(arr2[i]) > -1) {
arr1.splice(arr1.indexOf(arr2[i]), 1);
}
}
element.className = arr1.join(" ");
}
