我正在撰写的网页将用于显示幻灯片图片,其名称以及说明。这是在不同的页面中输入的。我面临的问题是我为幻灯片名称创建的数组被视为一个字符串。因此它不会返回幻灯片名称,而只返回一个数字。任何帮助将不胜感激
这是我的代码。我使用alert
来获取值的长度,这是当我看到数组被解析为单个字符串时

正如您将看到的那样,var name
数组与其他数组不同。这只是因为我尝试了一种不同的方法来查看它是否解决了问题。事实上它没有。
如果有人能指出我在这里正确的方向,我将不胜感激 我应该补充说,第一个结果显示正确,只有在调用函数时才会出现错误
我在浏览器中查看元素时获得的脚本。
<script>
var slide_no = 0;
var slides = ["..\/administration\/file_manager\/presentation\/Slides\/30_chair.jpg","..\/administration\/file_manager\/presentation\/Slides\/30_RTAC20150901_1.png","..\/administration\/file_manager\/presentation\/Slides\/30_RTAC20150901_2.png","..\/administration\/file_manager\/presentation\/Slides\/30_RTAC20150901_3.png","..\/administration\/file_manager\/presentation\/Slides\/30_RTAC20150901_4.png","..\/administration\/file_manager\/presentation\/Slides\/30_RTAC20150901_5.png"];
var desc = ["This is the the new 1st slide","Slide one","Slide two","Slide the third","Slide the fourth","Slide the fifth"];
var name1 = 'The new slide 1,Slide 1,Slide 2 ,Slide 3,slide 4,Slide 5';
var name = name1.split(",");
function nextSlide() {
if (slide_no < slides.length) {
slide_no++;
document.getElementById("display").src = slides[slide_no];
document.getElementById("func_slide_desc").innerHTML = desc[slide_no];
document.getElementById("func_slide_name").innerHTML = name[slide_no];
alert(name.length);
}
}
function prevSlide() {
if (slide_no > 0) {
slide_no--;
document.getElementById("display").src = slides[slide_no];
document.getElementById("func_slide_desc").innerHTML = desc[slide_no];
document.getElementById("func_slide_name").innerHTML = name[slide_no];
}
}
</script>
请注意,var name1等于一个长字符串,这不应该发生。
使用json_encode时,我在浏览器脚本中获得了以下结果
<script>
var slide_no = 0;
var slides = ["..\/administration\/file_manager\/presentation\/Slides\/30_chair.jpg","..\/administration\/file_manager\/presentation\/Slides\/30_RTAC20150901_1.png","..\/administration\/file_manager\/presentation\/Slides\/30_RTAC20150901_2.png","..\/administration\/file_manager\/presentation\/Slides\/30_RTAC20150901_3.png","..\/administration\/file_manager\/presentation\/Slides\/30_RTAC20150901_4.png","..\/administration\/file_manager\/presentation\/Slides\/30_RTAC20150901_5.png"];
var desc = ["This is the the new 1st slide","Slide one","Slide two","Slide the third","Slide the fourth","Slide the fifth"];
var name = ["The new slide 1","Slide 1","Slide 2 ","Slide 3","slide 4","Slide 5"];
function nextSlide() {
if (slide_no < slides.length) {
slide_no++;
document.getElementById("display").src = slides[slide_no];
document.getElementById("func_slide_desc").innerHTML = desc[slide_no];
document.getElementById("func_slide_name").innerHTML = name[slide_no];
alert(name.length);
}
}
function prevSlide() {
if (slide_no > 0) {
slide_no--;
document.getElementById("display").src = slides[slide_no];
document.getElementById("func_slide_desc").innerHTML = desc[slide_no];
document.getElementById("func_slide_name").innerHTML = name[slide_no];
}
}
</script>
答案 0 :(得分:1)
您可以使用您的阵列尝试json_encode
:
var name = <?php echo json_encode($slide_name_array); ?>;
<强>更新强>
我已为name
更改names
并且有效:/
答案 1 :(得分:0)
试试这个:
var name1 = '<?php implode(",",$slide_name_array); ?>';
var name = name1.split(",");
答案 2 :(得分:0)
在不知不觉地尝试各种其他方法后,所有这些都归结为从
重命名变量var name= <?php echo json_encode($slide_name_array); ?>;
要
var names = <?php echo json_encode($slide_name_array); ?>;
调整此变量的所有其他实例。让它成为一个教训。而是使用自己的变量!
