我有一些代碼,我試圖將一個div的id值傳遞給一個函數,該函數然後淡出第一個div然後淡入第二個。我知道該函數接受對象,因爲當我試圖顯示給它的值$ alert()時,我得到[Object object]。當單擊其中一個按鈕時,它將嘗試查找可見div的id,然後將其傳遞給fade函數,但它會找到id並將其保存在一個字符串中,我需要將其轉換爲對象。這裏是我的代碼:Jquery將字符串轉換爲對象
<script type="text/javascript">
$(function() {
$('#step1').fadeIn("slow");
$('#btn1').addClass("btn-primary active");
$('#btn1').click(function() {
\t var id = $(".editor .steps").filter(function() { //this gets the value of the active div and saves it into id.
\t \t if ($(this).css('display') == 'block') {
\t \t \t return true;
\t \t }
\t }).attr('id');
\t fade(id, $('#step1')) //tyring to send id and the the step1 to the fade function
});
$('#btn-step2-video').click(function() {
fade($('#step1'), $('#step2-video'));
$('#btn1').addClass("btn-primary");
$('#btn2').addClass("btn-primary active");
});
$('#btn-step2-picture').click(function() {
fade($('#step1'), $('#step2-picture'));
btn2.addClass("btn-primary active");
});
var fade = function(fadeout, fadein){
\t $(fadeout).fadeOut("slow");
$(fadein).fadeIn("slow");
}
});
</script>
Here is the HTML of the page:
<!-- begin snippet: js hide: false -->
<div id="steps">
\t <button id="btn1" type="button" class="btn btn-primary btn-lg btn-step">1</button>
\t <a class="btn-description">Choose type of ad</a>
\t <button id="btn2" type="button" class="btn btn-primary btn-lg btn-step">2</button>
\t <a class="btn">Confirmation & Payment</a>
</div>
<!--
Begining of editor
-->
<div class="editor">
<!--
Step 1 of the editor
-->
<div id="step1" class="steps" style="display:none;" >
\t <a id="btn-step2-video" style="position:fixed; top: 45%; left: 25%; cursor:pointer"><div class="btn-ad-choice ad-choice">
\t \t <br>
\t \t <p><b>Create a video ad:</b></p>
\t \t <video width="200" height="113" autoplay="autoplay" mute>
\t \t \t <source src="video/exemple.mp4" type="video/mp4">
\t \t \t Your browser does not support the video tag.
\t \t </video>
\t </div></a>
\t
\t <a id="btn-step2-picture" style="position:fixed; top: 45%; right: 25%; cursor:pointer"><div class="btn-ad-choice ad-choice">
\t \t <br>
\t \t <p><b>Create a picture ad:</b></p>
\t \t <img src="images/adexemple.jpg" alt="Exemple of a picutre ad" height="113" width="200">
\t </div></a>
</div>
<!--
Step 2 for video of the editor
-->
<div id="step2-video" class="steps" style="display: none; height:400px; width:100%; background:gray">
\t video
</div>
<!--
Step 2 for pictures of the editor
-->
<div id="step2-picture" class="steps" style="display: none;">
\t picture
</div>
<!--
end of editor
-->
</div>
編輯
我編輯我的JavaScript來:
$('#btn1').click(function() {
\t fade($(".editor .steps:visible"), $('#step1')); //tyring to send id and the the step1 to the fade function
});
