jquery replace not replacing all spaces with -
提问by Norman
Why is my jquery not replacing all spaces with a '-'. It only replaces the first space with a '-'
为什么我的 jquery 没有用'-'. 它只用一个替换第一个空格'-'
$('.modhForm').submit(function(event) {
var $this = $(this),
action = $this.attr('action'),
query = $this.find('.topsearchbar').val(); // Use val() instead of attr('value').
if (action.length >= 2 && query.length >= 2 && query.lenght <=24) {
// Use URI encoding
var newAction = (action + '/' + query.replace(' ','-'));
console.log('OK', newAction); // DEBUG
// Change action attribute
$this.attr('action', newAction);
} else {
console.log('To small to be any good'); // DEBUG
// Do not submit the form
event.preventDefault();
}
});

Try this:
尝试这个：
var str = 'a b c';
var replaced = str.split(' ').join('-');

It's: "if (action.length >= 2 && query.length >= 2 && query.length<=24) {"
它是：“if (action.length >= 2 && query.length >= 2 && query.length<=24) {”
Not: "if (action.length >= 2 && query.length >= 2 && query.lenght<=24) {"
不是：“if (action.length >= 2 && query.length >= 2 && query.lenght<=24) {”

You can try with custom function
您可以尝试使用自定义功能
String.prototype.replaceAll = function (searchText, replacementText) {
return this.split(searchText).join(replacementText);
};
var text = "This is Sample Text";
text.replaceAll(" ", "-");
//final output(This-is-Sample-Text)

Try this
尝试这个
query.replace(/ +(?= )/g,'-');
This still works, in case your query is undefiniedor NaN
这仍然有效，以防您的查询是undefinied或NaN

Replace all whitespace (including tabs, spaces, ...):
替换所有空格（包括制表符、空格等）：
query.replace(/\s/g, '_');
回答by Mike Samuel
String.prototype.replaceonly replaces the first when its first argument is a string. To replace all occurrences you need to pass in a global regular expression as the first argument.
String.prototype.replace仅在第一个参数是字符串时替换第一个。要替换所有出现的内容，您需要传入一个全局正则表达式作为第一个参数。
replace...
To perform a global search and replace, either include the g switch in the regular expression or if the first parameter is a string, include g in the flags parameter.
replace...
要执行全局搜索和替换，请在正则表达式中包含 g 开关，或者如果第一个参数是字符串，则在 flags 参数中包含 g。
Others have shown a number of regular expressions that work for varying definitions of "space."
其他人展示了许多适用于不同“空间”定义的正则表达式。
