我编写了一个jQuery代码来确定高度和宽度并单击功能。代码如下:
$(document).ready(function(){
console.log("Jquery is working!");
adjustBar();
$(window).on('resize', function() {
adjustBar();
})
$('#height').on('input change', function() {
var height = $(this).val();
if (height >= 30) {
var leftOffset = (Math.tan(45 * (Math.PI / 180)) * (height / 2) + 3) * -1;
$('.steps').css('height', height).css('line-height', height + "px").css('left', leftOffset + "px");
adjustBar();
}
});
$('.steps').on('click', function() {
$('.steps').removeClass('active');
$(this).addClass('active');
})
});
function adjustBar() {
var items = $('.steps').length;
var elHeight = $('.steps').height() / 2; //Division by 2 because each pseudo which is skewed is only 50% of its parent.
var skewOffset = Math.tan(45 * (Math.PI / 180)) * elHeight;
var reduction = skewOffset + ((items - 1) * 4);
var leftOffset = $('.steps').css('left').replace('px', '');
var factor = leftOffset * (-1) - 2;
$('.steps').css({
'width': '-webkit-calc((100% + 4px - ' + reduction + 'px)/' + items + ')'
}); // 4px for borders on either side
$('.steps:first-child, .steps:last-child').css({
'width': '-webkit-calc((100% + 4px - ' + reduction + 'px)/' + items + ' + ' + factor + 'px)'
}); // 26px because to make up for the left offset. Size of last-child is also increased to avoid the skewed area on right being shown
$('.steps span').css('padding-left', (skewOffset + 15) + "px");
$('.steps:first-child span, .steps:last-child span').css({
'width': '-webkit-calc(100% - ' + factor + 'px)'
});
}
运行该代码时,出现以下错误:
错误TS2362:算术运算的左侧必须为“ any”,“ number”,“ bigint”或枚举类型。 event-viewer / event-viewer.component.ts(34,35):错误TS2345:类型'string |编号字符串[]'不可分配给'字符串|类型的参数编号((this:HTMLElement,index:number,value:string)=>字符串|数字| void)'。 类型'string []'不能分配给类型'string |编号((this:HTMLElement,index:number,value:string)=>字符串|数字| void)'。 类型'string []'不能分配给类型'string'。 event-viewer / event-viewer.component.ts(49,20):错误TS2362:算术运算的左侧必须为'any','number','bigint'或枚举类型。
似乎height
,width
和leftoffset
被认为是字符串,但它们应该是根据元素在网页中的位置计算出的数值。我该如何解决这些错误?
答案 0 :(得分:1)
您应该将字符串值转换为数字。
您可以使用:var height = Number($(this).val());
