雪里已知春信至、寒梅点缀琼枝腻。 ---李清照-鼠标事件累加清除鼠标事件拾取封装某字符串后截取雪里已知春信至、寒梅

清除累加鼠标事件

document.addEventListener('click', clickFn)
const clcikFn = (event)=>{}

onUnmounted(async()=>{
    document.removeEventListener('click', cssHtmlFn)
}

鼠标事件拾取封装

/* 点击拾取模型事件 */
const getIntersects = (event: any, Group: any) => {
    if (!event.ctrlKey) return;
    const px = event.offsetX;
    const py = event.offsetY;
    //屏幕坐标转标准设备坐标
    const x = (px / window.innerWidth) * 2 - 1;
    const y = -(py / window.innerHeight) * 2 + 1;
    const raycaster = new THREE.Raycaster();
    raycaster.setFromCamera(new THREE.Vector2(x, y), camera);
    const intersects = raycaster.intersectObjects(Group);
    return intersects.length > 0;
}

export default getIntersects;

某字符串后截取

const getStringAfterCharacter = (str:string, character:any)=> {
    var parts = str.split(character);
    return parts.length > 1 ? parts.slice(1).join(character) : '';
}
 

let str = "user@example.com";
let character = "@";
let result = getStringAfterCharacter(str, character);
console.log(result); // 输出: example.com
