本文介绍了如何将工具提示添加到角度1 ui滑块的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧! 问题描述 29岁程序员,3月因学历无情被辞! 我正在创建一个角度ui滑块指令。但是无法为滑块控件添加工具提示。请建议 我尝试过: angular.module('lt.directives')。directive('slider',['$ templateCache','$ parseOptions',function($ templateCache,$ parseOptions){ //将这些默认值移动到value object var UPDATE_DELAY_MS = 100, NUM_TICKS = 20, MIN = 0, MAX = 5000, VALUE = 1500, STEPS = 100 , DEFAULT_HTML ='< div class =ui-slider-bwrap>'+ '< div class =ui-slider-ticks>'+ ' < span class =ui-tick-markng-style ={left:(5 * $ index)+ \'%\'}ng-repeat =tick in ticks/>'+ '< / div>'+ '< div class =ui-slider>< / div>'+ '< div class =ui-slider - 标签>'+ '< span class =minLabel> {{labelMin}}< / span>'+ '< span class =maxLabel> {{labelMax +(value ==最大&& showLabelMaxPlus&& +|| )}}< / span>'+ '< / div>'+ '< / div>'; 返回{ require:'ngModel',范围:{ value:'= ngModel', defaultValue:'=?', sliderData:'=?', min:'=?', max:'=?', step:'=?', labelMin:' @', labelMax:'@'},模板:function(element,attrs){ //将来,根据attrs.slider $改变模板b $ b返回DEFAULT_HTML; }, link:function(scope,element,attrs,ngModel){ //如果不存在则设置默认值 _.defaults(范围,{值:scope.defaultValue, labelMin:'0%', labelMax:'100%'}); //如果min / max未定义,则不设置隔离范围, //因为它将导致不可赋值的表达式错误。 if(_.every([scope.min,scope.max],angular.isDefined)){ _.defaults(范围,{ min:MIN, max :MAX }); } //只检查属性是否存在 scope.showLabelMaxPlus = angular.isDefined(attrs.showLabelMaxPlus); var staggerStepObj = scope。$ eval(attrs.staggerStep), modelMapObj = scope。$ eval(attrs.modelMap), parsedOptions = angular.isDefined(attrs.sliderOptions) )?
