问题:如何获取array数组的长度?
array: [{
mode: ‘scaleToFill’,
text: ‘scaleToFill:不保持纵横比缩放图片,使图片完全适应’
}, {
mode: ‘aspectFit’,
text: ‘aspectFit:保持纵横比缩放图片,使图片的长边能完全显示出来’
}, {
mode: ‘aspectFill’,
text: ‘aspectFill:保持纵横比缩放图片,只保证图片的短边能完全显示出来’
}, {
mode: ‘top’,
text: ‘top:不缩放图片,只显示图片的顶部区域’
}, {
mode: ‘bottom’,
text: ‘bottom:不缩放图片,只显示图片的底部区域’
}, {
mode: ‘center’,
text: ‘center:不缩放图片,只显示图片的中间区域’
}, {
mode: ‘left’,
text: ‘left:不缩放图片,只显示图片的左边区域’
}, {
mode: ‘right’,
text: ‘right:不缩放图片,只显示图片的右边边区域’
}, {
mode: ‘top left’,
text: ‘top left:不缩放图片,只显示图片的左上边区域’
}, {
mode: ‘top right’,
text: ‘top right:不缩放图片,只显示图片的右上边区域’
}, {
mode: ‘bottom left’,
text: ‘bottom left:不缩放图片,只显示图片的左下边区域’
}, {
mode: ‘bottom right’,
text: ‘bottom right:不缩放图片,只显示图片的右下边区域’
