消除特定事件发生后方的特征
原标题:remove characters in string after specific occurrence

you你们可以帮助我。

我有动态的ur,我需要一些 j子,在具体发生特性之后,基本上把扼杀放在次要位置。

我有这ur。

Assessment/testdir2/ TestDIR3/lecture slides 1as.pdf

并且,我需要删除<代码>2nd slash之后的一切,包括第2句斜线。

我如何这样做?

最佳回答

一项非常基本的联合解决办法:

function removeAfterSlash(word, numberOfElements) {
    var splitWord = word.split( / );
    var newWord =   ;
    for(var i = 0; i < numberOfElements; i++) {
        if(i != (numberOfElements - 1)) {
            newWord += splitWord[i] +  / ;
        } else {
            newWord += splitWord[i];
        }   
    }
    document.write(newWord);
}
removeAfterSlash( Assessment/testdir2/TestDIR3/lecture slides 1as.pdf , 1);

简单地将这个词分成一个阵列,看上<条码>/,然后,你可以加入你需要的内容。 这项职能是用词和你希望团结在一起的许多部分。

问题回答

引证:

var url= "Assessment/testdir2/TestDIR3/lecture slides 1as.pdf"
var locs = myString.split( / );
var newUrl = "";
for (var i = 2; i < locs.length; i ++) {
    newUrl += "/" + locs[i];
}

这样,这种方法将忽视头两个方面,不管你在导游中拥有多少其他方面。
