Je cherche l'info-bulle angulaire 2 qui devrait ajuster automatiquement la position elle-même (de gauche et de droite au moins) dans mobile ou quand la fenêtre est redimensionnée devrait être visible sur l'écran complètement. Je partage mon code actuel sur Plunker, apprécie si quelqu'un peut m'aider à ce sujet. Merci.L'info-bulle angulaire 2 devrait ajuster automatiquement la position elle-même dans mobile ou quand la fenêtre est redimensionnée
Cette fonction de position J'utilise:
private positionElements(hostEl: HTMLElement, targetEl: HTMLElement, positionStr: string, appendToBody: boolean = false): { top: number, left: number } {
let positionStrParts = positionStr.split("-");
let pos0 = positionStrParts[0];
let pos1 = positionStrParts[1] || "center";
let hostElPos = appendToBody ? this.offset(hostEl) : this.position(hostEl);
let targetElWidth = targetEl.offsetWidth;
let targetElHeight = targetEl.offsetHeight;
let shiftWidth: any = {
center: function(): number {
return hostElPos.left + hostElPos.width/2 - targetElWidth/2;
},
left: function(): number {
return hostElPos.left;
},
right: function(): number {
return hostElPos.left + hostElPos.width;
}
};
let shiftHeight: any = {
center: function(): number {
return hostElPos.top + hostElPos.height/2 - targetElHeight/2;
},
top: function(): number {
return hostElPos.top;
},
bottom: function(): number {
return hostElPos.top + hostElPos.height;
}
};
let targetElPos: { top: number, left: number };
switch (pos0) {
case "right":
targetElPos = {
top: shiftHeight[pos1](),
left: shiftWidth[pos0]()
};
break;
case "left":
targetElPos = {
top: shiftHeight[pos1](),
left: hostElPos.left - targetElWidth
};
break;
case "bottom":
targetElPos = {
top: shiftHeight[pos0](),
left: shiftWidth[pos1](this.useAlternateMobileTooltip)
};
break;
default:
targetElPos = {
top: hostElPos.top - targetElHeight,
left: shiftWidth[pos1]()
};
break;
}
return targetElPos;
}
