如何使用 jquery 添加 href 的字符串值？

Question

我有一個帶有 href 的輸入按鈕。 我需要在輸入文本框的 href 中的最后一個 / 之后添加一個字符串。 使用 jquery 如何實現這一點？ 這是代碼：

//This is the Search Button
$('#switch-fighter-search-button-link').attr("href","/fighters/search/");

//This is the Input box
var sft = $('$switch-fighter-text').val();

Answer 1

$('#switch-fighter-search-button-link').attr("href","/fighters/search/" + $('$switch-fighter-text').val());

Answer 2

嘗試這個：

$('$switch-fighter-text').keyup(function(){

     $('#switch-fighter-search-button-link').get(0).href = 
                                                 "/fighters/search/"+this.value;

});

這將在搜索框更改時更新

Answer 3

抓住這兩個值並將它們連接起來（用？分隔，我猜），如下所示：

var head = $('#switch-fighter-search-button-link').attr("href"); // get existing href
var tail = $('#switch-fighter-text').val(); // get input value
var nhref = head + '?' + tail  // join them together, separated by a ? character
$('#switch-fighter-search-button-link').attr('href', nhref); // update the button with the new href value

Answer 4

Append 字符串。

//save the base string somewhere at the beginning of your jquery
var basehref = $('#switch-fighter-search-button-link').attr("href","/fighters/search/");

//add a event handler when the text box is changed to update the button
$('#switch-fighter-text').change(function() {
    var sft = basehref + $(this).val();

    $('#switch-fighter-search-button-link').attr("href", sft);
});
