The example in this article shares jquery customization with everyone. The specific code for displaying the number of messages is for your reference. The specific content is as follows
A small functional control is simply implemented according to the needs. Extension is not supported for the time being.
$（"xxxxxxx"）.iconCountPlugin（options, start, isOffset) {

(function ($, window, document, undefined) {
var inforCountShow = function (target, option, isOffset) {
this.$element = target;
var str = "<span class = 'infor-count'></span>";
var offsetleft = $(this.$element).offset().left;
var offsetTop = $(this.$element).offset().top;
var targetWidth = $(this.$element).width();
var targetHeight = $(this.$element).height();
var left = "",
top = "";
if (!isOffset) {
left = offsetleft + targetWidth - 18;
top = offsetTop - 5;
} else {
left = targetWidth + 13;
top = targetHeight - 3;
}
$(this.$element).after(str);
this.defaults = {
'display': 'inline-block',
'width': '18px',
'height': '18px',
'position': 'absolute',
'backgroundColor': '#f43530',
'color': '#fff',
'borderRadius': '15px',
'textAlign': 'center',
'fontSize': '12px',
"left": left,
"top": top,
"cursor": 'auto',
'margin':'auto'
};
this.options = $.extend({}, this.defaults, option);
this.createdDom = $(str);
}
inforCountShow.prototype = {
//手动设置
changeStyle: function () {
return $(this.$element).next().css({
'display': this.options.display,
'width': this.options.width,
'height': this.options.height,
'position': this.options.position,
'backgroundColor': this.options.backgroundColor,
'color': this.options.color,
'borderRadius': this.options.borderRadius,
'zIndex': this.options.zIndex,

'fontSize': this.options.fontSize,
"left": this.options.left,
"top": this.options.top,
'lineHeight': this.options.lineHeight,
"cursor": this.options.cursor,
"margin": this.options.margin
});
},
//浏览器窗口大小改变自适应，默认生效
onResize: function (target, isOffset) {
$(window).resize(function () {
var newOffsetleft = $(target).offset().left;
var newOffsetTop = $(target).offset().top;
var newTargetWidth = $(target).width();
var newTargetHeight = $(target).height();
var newleft = "", newTop = "";
if (!isOffset) {
newleft = newOffsetleft + newTargetWidth - 18;
newTop = newOffsetTop - 5;
} else {
newleft = newTargetWidth + 13;
newTop = newTargetHeight - 3;
}
$(target).next().css({
"left": newleft,
"top": newTop
});
});
},
//数值溢出，当消息数量超过99时显示 "..."
valueOverflow:function() {
var value = $(this.$element).next().text();
if (null != value && value>99) {
$(this.$element).next().text("...");
}
},
//绑定事件，可以接受事件对应外部方法
bindEvent: function () {
var that = this;
if (!that.createdDom) return;
this.createdDom.off('click').on('click', function () {
if (that.options.click) {
// that.options.click();
} else {
}
});
}
}
//调用
$.fn.iconCountPlugin = function (options, start, isOffset) {
//三个参数，自定义样式，是否禁止图标位置随浏览器窗口变化而变化，是否禁用偏移量
return $(this).each(function () {
var infor = new inforCountShow(this, options, isOffset);
if (!start) {
infor.onResize(this, isOffset);
}
infor.changeStyle();
infor.valueOverflow();
infor.bindEvent();
});
}
})(jQuery, window, document);The above is what I compiled for everyone. I hope it will be helpful to everyone in the future.
