log(upperStr); // "I LIKE TO EAT APPLES." let titleStr = str.toTitleCase(); console.log(titleStr); // should print "I Like To Eat Apples." but in fact fails. split(separator) This splits a string into an array of substrings, based on the separator, which can be one ...

Don’t forget to explicitly name the expression, regardless of whether or not the name is inferred from the containing variable (which is often the case in modern browsers or when using compilers such as Babel). This eliminates any assumptions made about the Error’s call stack. (Discussion)...
scrollTo(scrollLeft, scrollTop) scrollTo( options ) 其中options是一个对象 {left: scrollLeft数据, top: scrollTop数据, behavior: "smooth"} 设置behavior: smooth就是由动画滚动效果扩展知识点 1.原生JS基于window.scrollTo()封装垂直滚动动画工具函数,可应用与锚点定位、回到顶部等操作。
Then all the typing and tooling is highlighted when referencing this library, and that’s the case with any of the major libraries you may find at the DefinitelyTyped GitHub repository. A great feature the compiler brings in declaration files is the ability to auto-traverse the references. What...
According to Heinz Scheuring: “The Sencha grid is the key element of resSolution and hyperManager. Ext JS and its other components have really helped us refine our business approach.”– You can read complete case studies here. Conclusion JavaScript is undoubtedly the most used scripting ...
Returns to the caller before the modal has actually been hidden (i.e. before the hidden.bs.modal event occurs). Copy $('#myModal').modal('hide') .modal('handleUpdate') Readjusts the modal's positioning to counter a scrollbar in case one should appear, which would make the modal jump...
Note: This example applies to legacy JavaScript engines only—modern ones have garbage collectors (GCs) that are smart enough to handle this case. Consider the following code: vartheThing =null;varreplaceThing =function() {varpriorThing = theThing;// Hold on to the prior thingvarunused =func...
