我正在D3中工作...基于输入我想从数据库中获取数据到D3 ..当我在输入字段中输入一些单词并单击提交工作正常...在D3中没有问题...但是当我改变输入字段时，在提交按钮中没有任何操作..它想要我刷新以搜索新的单词...在任何错误的这样我在这里使用了AJAX ..当基于D3的输入获取数据时Ajax无法工作
$(function (all) {
$('form').on('submit', function (e) {
e.preventDefault();
var t=$('form').serialize();
var u='http://localhost:8888/saff/indexi.php?'+t;
$.ajax({
url:u,
async:true,
success:function(data){
funn();
}
});
function funn(){
d3.json(u, function(treeData) {
//d3 code
});
}
});
});
其次，当我改变的形式输入作为
<form name="editorForm" id="formi">
<input type="text" name="editor"
id="editor" onchange="document.getElementById('formi').submit();"/>
<input type="submit"value="butn">
<br />
</form>
型字在外地和SUBM它只是使在URL变化 http://localhost:8888/saff/keyy.html到http://localhost:8888/saff/keyy.html?editor=அகடம்并没有在网页 我应该如何使用AJAX在D3去D3基于输入从PHP数据显示，无需刷新页面
问题是 *当提交第一个词它在WEBPAGE中正确设计时 *当我更改输入文本时，第二个设计来自第一个设计 为什么ajax不工作??? UPDATE 我的完整代码

终于出现在控制台但输入改变D3的设计没有路径错误显示下面的第一个输入设计 任何想法？为什么AJAX是不是在这里工作？
谢谢您先生，为您的回应和兴趣在这里...但遗憾地说，仍然问题不清楚..plz在问题中看到我的控制台图片..控制台中有一些变化。 。但不在网页 – prog
你的路径中的文件实际上是否包含“i”'indexi.php'？ – Rick
是的，我把php文件命名为indexi.php .. – prog
