Jquery: Replace string with values from an array
提问by Bennett
Say I have something like this:
说我有这样的事情：
var array = [cat,dog,fish];
var string = 'The cat and dog ate the fish.';
I want to clear all those values from a string
我想从字符串中清除所有这些值
var result = string.replace(array,"");
The result would end up being: The and ate the .
结果将是： The and ate the .
Right now, replace()appears to only be replacing one value from the array. How can I make it so all/multiple values from the array are replaced in the string?
现在，replace()似乎只替换数组中的一个值。我怎样才能让它在字符串中替换数组中的所有/多个值？
Thanks!
谢谢！

You either createa custom regexpor you loop over the string and replace manually.
您要么创建自定义正则表达式，要么遍历字符串并手动替换。
array.forEach(function( word ) {
string = string.replace( new RegExp( word, 'g' ), '' );
});
or
或者
var regexp = new RegExp( array.join( '|' ), 'g' );
string = string.replace( regexp, '' );

string.replace(new RegExp(array.join("|"), "g"), "");
