我正在创建一个用户界面,用户可以通过点击所需的纹理图片来更改所选对象的纹理。
问题是我只能使用数组中添加的最后一个纹理。
这是我的php,它列出了我指定文件夹中的纹理:
<ul id="textureH">
<script type="text/javascript">
texArray = [];
</script>
<?php
for($index=0; $index < $indexCount; $index++) {
$extension = substr($dirArray[$index], -3);
if ($extension == 'jpg'){
$texName = $dirArray[$index];
$texId = "texture". $index;
?>
<script type="text/javascript">
var texName = '<?php echo $texName ?>';
var texId = '<?php echo $texId ?>';
texArray.push(texId);
</script>
<?php
echo "<li id='".$texId."'><table><tr><td><img class='texture-image-list' src='img/" . $texName . "' alt='Image' /></td><td><span id='texture-item-name'>" . $texName . "</span></td></tr></table></li>";
}
}
?>
</ul>
这是我的功能:
var uTexture = document.getElementById(texId);
uTexture.addEventListener("click", updateTexture, false);
function updateTexture(){
var texMap = "./img/" + texName;
for (var i in texArray) {
if ((texArray[i] == texId) && (SELECTED instanceof THREE.Mesh)) {
SELECTED.material.map = THREE.ImageUtils.loadTexture(texMap);
SELECTED.material.needsUpdate = true;
}
}
}
我认为问题来自数组。
答案 0 :(得分:0)
感谢2pha我可以实现我想要的目标。
这是我的新代码: (php / html)
<div class="right-panel-textures">
<h3 id="cat-hierarchy">Textures</h3>
<?php
$myDirectory = opendir('img/textures');
while($entryName = readdir($myDirectory)) {
$dirArray[] = $entryName;
}
sort($dirArray);
closedir($myDirectory);
$indexCount = count($dirArray);
?>
<ul id="textureH">
<?php
for($index=0; $index < $indexCount; $index++) {
$extension = substr($dirArray[$index], -3);
$texName = $dirArray[$index];
$texId = "texture". $index;
if ($extension == 'jpg'){
?>
<script type="text/javascript">
var texName = '<?php echo $texName ?>';
var texId = '<?php echo $texId ?>';
</script>
<?php
echo "<li class='texture-single-item' data-texture-name='".$texName."' data-texture-id='".$texId."' id='texture-single-item'><table><tr><td><img class='texture-image-list' src='img/textures/" . $texName . "' alt='Image' /></td><td><span id='texture-item-name'>" . $texName . "</span></td></tr></table></li>";
}
}
?>
</ul>
</div>
(和JavaScript)
var uTexture = document.getElementById("texture-single-item");
uTexture.addEventListener("click", updateTexture, false);
function updateTexture(){
$(".texture-single-item").bind("click", function(event) {
var nameT = $(this).attr("data-texture-name");
if (SELECTED instanceof THREE.Mesh) {
var texMap = "./img/textures/" + nameT;
SELECTED.material.map = THREE.ImageUtils.loadTexture(texMap);
SELECTED.material.needsUpdate = true;
}
});
}
谢谢:)
