我想读取一个SVG文件并从该文件中获取SVG标记(因为我想在html中显示svg,例如<div><svg>...</svg></div>没有xml标题).

并在浏览器中显示此svg标签,如HTML - 打印此SVG标签,如SVG图像.贝塞尔现在我输错了输出" DOMNodeList Object([length] => 1) ".

PHP

$doc = new DOMDocument();
$doc->load('http://example.com/logo.svg');
$svg = $doc->getElementsByTagName('svg');

echo "<div style='width: 100%, height: 100%; '>";
print_r($svg); // DOMNodeList Object ( [length] => 1 ) 
echo "</div>";

我有一些DIV.在这些DIV中有一些文本,图像,标签......当需要点击文本时,我需要显示"警报".不是图像,不是其他标签,不是其他标签中的文本......只是DIV内的文本.如何用jQuery做到这一点？

jsFiddle例子.

HTML

<div style="background-color:PapayaWhip;">Some text. 
 <img src="http://ynternet.sk/test2/close_1.jpg" /> 
 <img src="http://ynternet.sk/test2/close_2.jpg" /> 
</div> 
<div style="background-color:Moccasin;">This are letters 
 <em>and this are not.</em> 
 Hello again!
</div> 
<div style="background-color:LightGoldenRodYellow;">
 <img src="http://ynternet.sk/test2/close_1.jpg" />
 <img src="http://ynternet.sk/test2/close_2.jpg" />
 Letters in new line.
 <img src="http://ynternet.sk/test2/close_1.jpg" />
 <img src="http://ynternet.sk/test2/close_2.jpg" /> 
</div> 
<div style="background-color:Wheat;">New letters in another line.</div>

CSS

div {
  padding:10px 0px 0px 20px;
  font-family:Verdana;
  height:40px;
}
em{
  color:red;
}

我想从输入元素中获取值作为数字并用 jQuery 计算它们。我正在尝试，但结果不是十进制的。如何解决这个问题？

HTML

<input name="test1" value="1.77" type="hidden" />
<input name="test2" value="1.23" type="hidden" />

jQuery

var a = parseInt($( "input[name='test1']").val(), 10);
var b = parseInt($( "input[name='test2']").val(), 10);
alert( a + b ); // should be 3, but it is only 2

这是一个示例 -> jsfiddle 示例

当你add new按下按钮时,jQuery将新dragrable DIVs的插入CONTAINER.当我点击其中一些时DIVs,我想改变z-index价值.但jQuery无法将z-index值作为数字.它只显示'auto'...是否有解决方案显示真正的z-index值和increase it by 1？

jsFiddle示例 - http://jsfiddle.net/ynternet/84nVQ/10/

HTML

<div id="add" style="background:yellow; width:100px;"> add new </div>
<div id="container"> </div>

jQuery的

function handler() {
    if ($(this).find("#menu").length) {
        return;
    }
    var currentIndex = $(this).css('z-index');
    alert(currentIndex);
    var newIndex = currentIndex + 1;
    alert(newIndex);
    $(this).css('z-index', newIndex);
}
$("#add").on({
    click: function(e) {
        var timestamp = Date.now();
        var posx = Math.floor(Math.random() * 400);
        var posy = Math.floor(Math.random() * 400);
        $('#container').append(function() { …

当我点击SVG时,我想从这个SVG获得所有PATH的列表.然后从每个PATH获得FILL.但似乎,jquery doues不知道归因于FILL.

在库TCPDF中.如何通过命令"setlinestyle"设置不同的边框,使细胞看起来像这样:

CSS

/* top */
border-top-width="1" 
border-top-style="solid" 
border-top-color="rgba(0, 255, 0, 1)"
/* right */
border-right-width="2" 
border-right-style="dotted" 
border-right-color="rgba(255, 0, 255, 1)" 
/* bottom */ 
border-bottom-width="3" 
border-bottom-style="solid" 
border-bottom-color="rgba(0, 0, 255, 1)"
/* left */
border-left-width="4" 
border-left-style="solid" 
border-left-color="rgba(255, 0, 255, 1)" 

所有边框都有一种样式的PHP命令

$pdf->SetLineStyle(array('width' => 0.5, 'cap' => 'butt', 'join' => 'miter', 'dash' => 4, 'color' => array(255, 0, 0)));

$text="DUMMY";
$pdf->Cell(0, 0, $text, 1, 1, 'L', 1, 0);

我想通过TCPDF设置一些文本块.但是我的字体大小有些问题.第一个文本块在xy/5-5上,字体大小为5到.但它比5更小.TCPDF中的字体大小与其他维度的字体大小不同？

PHP

$text1 = 'AAAg';
$text1_x = 5;
$text1_y = 5;
$text1_font_size = 5;

$text2 = 'BBBg';
$text2_x = 10;
$text2_y = 10;
$text2_font_size = 10;

$text3 = 'CCCg';
$text3_x = 15;
$text3_y = 15;
$text3_font_size = 15;
// I tried  $pdf->Cell and $pdf->Text... both are doing the same...

网络示例.

我想从AJAX加载的图像中选择图像到某个模态窗口.选择图像后,将选定的图像插入我的页面"DIV id = container".

1. 哪个模态插件更适合这个？
2. 这有一些实际的例子吗？(我没找到......)
3. 那么Avgrund模态插件呢,我能用这个插件制作吗？(相反,它是非常好的效果,我喜欢)

我需要保存由 TCDPF 生成的 DPF 文件，保存此文件后我需要将有关它的信息发送到另一个脚本。如何检查PDF文件保存到文件夹是否完成？

$pdf->Output('folder/example_006.pdf', 'F');

我有很多带有“数据值”属性的 div。但只有一个类名为“.selected”。我需要用两者制作选择器。数据 + 类名。

如何使用数据属性和类名制作选择器？

HTML

<div data-value="x">Click Me!</div>
<div data-value="y">Click Me!</div>
<div class='selected' data-value="z">Click Me!</div>
<div data-value="w">Click Me!</div>

jQuery

alert( $("div[data-value] .selected").data('value') );  // this is wrong way...
